As AI workloads continue to drive unprecedented demand for bandwidth and connectivity, traditional optical architectures face increasing challenges in power consumption, thermal management, signal integrity, and system density. By bringing high-performance optical interfaces closer to the switching and compute silicon, NPO and CPO architectures offer a path toward significantly higher bandwidth density and improved system-level efficiency.
“Near-packaged and co-packaged optics are entering their initial ramp in 2026, and the shift toward NPO and CPO architectures reflects a broader industry response to the power and scaling bottlenecks facing AI back-end networks,” said Sameh Boujelbene, vice president, data center switch and AI networks market research at Dell’Oro Group. “As hyperscalers move these architectures from trials to deployment, the underlying TIA and driver technology becomes a critical enabler of that transition.”
Designed for 224G Linear Optical Architectures
Semtech’s new products include the GN1838L and GN42T380, the industry’s first linear octal TIAs, and the GN42M380 linear octal Mach-Zehnder Modulator (MZM) driver, optimized for 1.6T, 3.2T, 6.4T, and 12.8T optical engines (OEs). The 224G TIA and driver portfolio optimizes for CEI-224G-Linear and Open CPX interfaces and linear architectures, with very strictly specified space and power dissipation requirements.
“AI infrastructure is fundamentally changing the requirements for optical connectivity,” said Amit Thakar, vice president, signal integrity product marketing at Semtech. “At 224G per lane, designers need more than bandwidth. They need signal integrity, power efficiency, flexibility, and system-level visibility. Our TIAs and driver solutions are purpose-built to give NPO and CPO developers the building blocks to scale optical I/O while addressing the power and density challenges of next-generation AI systems.”
Enabling NPO and CPO at Scale
The GN1838L TIA offers 500µm channel pitch and the GN42T380 offers a 375µm channel pitch, giving customers flexibility in OE design choices. These TIAs can be used in side-by-side configuration with the photonics integrated circuit (PIC) or placed directly on top of the PIC, giving customers maximum flexibility. Both TIAs include an Automatic Gain Control (AGC) stage and output driver featuring programmable Continuous Time Linear Equalization (CTLE) and support both Manual and Automatic Gain Control (MGC and AGC) modes. The bandwidth is optimized to achieve low peaking, low input referred noise (IRN), and good group delay with minimal distortion. The devices offer several programmable performance optimization features, including output equalization, and are designed to interface with a wide variety of optical input signals, while optimizing performance at the switch or ASIC input.
The GN42M380 driver offers 375µm channel pitch and supports a variety of modulators, including Silicon Photonics (SiPho), Indium Phosphide Mach-Zehnder Modulator (InP MZM) and Thin-Film Lithium Niobate (TFLN). The GN42M380 delivers low group delay and minimal Total Harmonic Distortion (THD), ensuring superior driver performance. Programmable Continuous Time Linear Equalization (CTLE) is included to help compensate for intersymbol interference (ISI) due to the input signal transmission path. It also offers flexible biasing, making it compatible with MZMs from various vendors. The driver output swing is configurable, and on-chip equalization enables precise tuning of electrical and optical performance.
The TIA and driver family integrates several diagnostics and performance tuning features that can be accessed through device pads and the I²C interface.

CONCORD, N.H. (AP) — Lily Tang Williams won the Republican primary in New Hampshire’s 2nd Congressional District for a second time Tuesday.
Tang Williams previously led the Libertarian Party in Colorado and unsuccessfully ran for office there before moving to New Hampshire in 2019. She finished third in the 2nd District’s GOP primary in 2022 and was the nominee two years ago, losing to Democrat Maggie Goodlander.
In all her campaigns, Tang Williams has emphasized her impoverished childhood in China, her immigration to the U.S. as a student and becoming a citizen 30 years ago. She defeated three other candidates to win the nomination.

CONCORD, N.H. (AP) — U.S. Rep. Maggie Goodlander won the Democratic primary Tuesday as she seeks a second term in New Hampshire’s 2nd Congressional District.
Goodlander, a former White House aide and U.S. Naval Reserve intelligence officer, defeated Paige Beauchemin, a registered nurse and progressive state lawmaker.
Last November, after the Trump administration deployed the National Guard to patrol American cities, Goodlander joined fellow Democrats with military backgrounds in an online video advising members of the U.S. military that they should refuse to carry out “illegal orders.”
Though Goodlander is in her first term, the seat has been held by a Democrat for the last seven election cycles.

CONCORD, N.H. (AP) — Anthony DiLorenzo, a Trump-backed businessman making his first run for office, won the Republican primary Tuesday for the open seat in New Hampshire’s 1st Congressional District.
DiLorenzo, founder of a chain of car dealerships, emphasized his business background on the campaign trail, saying it made him the most qualified candidate despite his lack of political experience. President Donald Trump endorsed him in July, calling him a successful entrepreneur who will champion an economic “Golden Age.”
DiLorenzo defeated three other candidates hoping for a chance at succeeding U.S. Rep. Chris Pappas, a four-term Democrat who is giving up the seat to run for the Senate.

CONCORD, N.H. (AP) — New Hampshire Gov. Kelly Ayotte easily won her Republican primary Tuesday as she seeks a second term.
Ayotte will face Democrat Cinde Warmington in November. Warmington, who serves on the governor’s Executive Council approving state contracts and judicial nominations, was unopposed in the Democratic primary.
Ayotte became the third woman to be elected governor of New Hampshire in 2024, following Democrats Jeanne Shaheen and Maggie Hassan. Like them, she also served in the U.S. Senate, losing her seat to Hassan in 2016 after one term.
She succeeded fellow Republican Chris Sununu, who did not seek a fifth two-year term.
THIS IS A BREAKING NEWS UPDATE. AP’s earlier story follows below.
CONCORD, N.H. (AP) — U.S. Rep. Chris Pappas of New Hampshire won the Democratic nomination Tuesday in the race to succeed U.S. Sen. Jeanne Shaheen, a three-term Democrat who didn’t seek reelection.
Pappas, who is giving up his House seat after four terms, entered the race as the frontrunner, dwarfed the other four candidates in fundraising and was endorsed by former Vice President Kamala Harris. But as the election neared, he faced increased competition from Karishma Manzur, a research scientist and democratic socialist who argued he was too beholden to special interests.
Pappas currently represents the 1st Congressional District, which covers the eastern half of the state and includes its largest city. He previously served on the governor’s Executive Council, a five-member panel that approves state contracts and judicial nominees.
THIS IS A BREAKING NEWS UPDATE. AP’s earlier story follows below.
CONCORD, N.H. (AP) — Former U.S. Sen. John E. Sununu won New Hampshire’s Republican primary Tuesday for the open seat he lost 18 years ago.
Sununu defeated another former senator, Scott Brown, and six other candidates to advance to the general election. He hopes to replace U.S. Sen. Jeanne Shaheen, a Democrat who ousted him in 2008 and is retiring after three terms.
Sununu, who also served three terms in the House, was endorsed by President Donald Trump even after calling him “a loser” during the 2024 presidential campaign. He had the backing of the GOP establishment in a state Republicans view as a key opportunity to flip a seat in their attempt to retain control of the Senate.
Brown, who previously represented Massachusetts and unsuccessfully challenged Shaheen in 2014, accused Sununu of coasting on his name. Sununu’s father and younger brother are former governors.
THIS IS A BREAKING NEWS UPDATE. AP’s earlier story follows below.
CONCORD, N.H. (AP) — New Hampshire primary voters are choosing candidates for Congress, governor and the 424-seat state Legislature on Tuesday, and incumbents aren’t the only familiar names on the ballot.
U.S. Sen. Jeanne Shaheen’s decision to not seek reelection created a cascade of competitive races. Two of the eight Republicans hoping to replace the three-term Democrat are former U.S. senators she previously defeated: John E. Sununu and Scott Brown. The five-way race for the Democratic nomination includes U.S. Rep. Chris Pappas, whose departure from his 1st Congressional District seat in turn attracted a crowd of candidates.
Shaheen’s daughter, Stefany Shaheen, is among those seeking the Democratic nomination for Pappas' seat, along with former candidate Maura Sullivan. Several other candidates in top races also are making repeat appearances.
Sununu, who spent six years in the U.S. House and one term in the Senate before being ousted by Shaheen in 2008, has this time focused on themes including affordability for housing, healthcare and energy, holding Congress accountable and constituent service.
“I’ve been out of politics for 17 years. I’m not worried about reelection,” he said during a campaign stop last month. “I don’t need an appointment or a job. I don’t need to make anyone happy. I need to do one thing: Stand up for the people of New Hampshire.”
Brown previously represented Massachusetts, where he won a special election in 2010 after the death of Sen. Ted Kennedy before losing in 2012. He unsuccessfully challenged Shaheen in 2014 and served as ambassador to New Zealand and Samoa during President Donald Trump's first term.
In a July interview, he said he decided to run again because New Hampshire Republicans have no representation in Congress and because, in his view, his experience as a veteran, lawmaker, ambassador and grandfather is unmatched.
He accuses Sununu — whose father and younger brother are former governors — of coasting on his name. Sununu also has the backing of Trump, despite having called him “a loser” in 2024, but Brown said that will just make him beholden to the president and other special interests.
“I’m the only truly independent candidate here who can actually vote on anything with a clear conscience and with New Hampshire’s best interests at heart,” Brown said.
Jim Loomis, 83, of Bow, said he backed Brown in 2014 but not on Tuesday because “he never got traction back again." He acknowledged Sununu had been out of politics for even longer but still voted for him.
“I think what he's done for work over the years has kept him close enough to what's going on, and then with his family ties, I just think he's got a more stable base,” he said.
Pappas, who is giving up his House seat after four terms, raised twice as much money as Sununu and Brown combined and dwarfed his Democratic primary opponents, as well. He also enjoyed a wide lead in polls, though recently lost some ground to scientist and democratic socialist Karishma Manzur.
Kristin Selesnick, 41, of Bow, said Pappas was a “fine” candidate but she doesn't like that he accepts money from super PACs and that he voted “present” on a measure to restrict weapons sales to Israel instead of voting no. She voted for Manzur.
“I just like her whole platform,” she said. “I think she would be a great voice for the Granite State.”
Stefany Shaheen and Sullivan are the leading candidates among seven seeking the Democratic nomination in the 1st District.
Shaheen is a former city councilor in Portsmouth. She founded a business to help people with chronic medical conditions after one of her daughters was diagnosed with Type 1 diabetes. She also is part of a bio-tech initiative in New Hampshire to advance regenerative medicine.
Sullivan is a former Marine and Iraq War veteran who served as an assistant secretary at the Department of Veterans Affairs under President Barack Obama. A vice chair of the New Hampshire Democratic Party, Sullivan ran for the 1st District seat in 2018, losing in an 11-candidate primary to Pappas in his first congressional bid.
The Republican field of four candidates includes political newcomer Anthony DiLorenzo, who owns a chain of car dealerships and has been endorsed by Trump, and Hollie Noveletsky, a veteran and nurse practitioner who runs a steel fabrication company and ran for the same seat two years ago.
In the 2nd District, first-term Democratic incumbent Rep. Maggie Goodlander faces a primary challenge from Paige Beachemin, a progressive state lawmaker and nurse. The four-person Republican primary field includes Lily Tang Williams, who was the nominee two years ago and is making her third attempt at the seat.
In contrast to the all-Democratic congressional delegation, Republicans dominate state government.
Republican Gov. Kelly Ayotte faces two little-known opponents in her primary as she seeks a second two-year term. Cinde Warmington, a healthcare attorney, is unopposed for the Democratic nomination.
Voters also will be nominating candidates for the entire state Legislature, where Republicans hold a roughly 40-vote majority in the 400-member House and outnumber Democrats in the Senate 16-8.
Accustomed to going first when it comes to presidential primaries, New Hampshire is among the last states to hold state-level primary elections, leaving the winners just eight weeks to woo voters before Nov. 3. But legislation passed this year moves future state primaries to the second Tuesday in June.
