Retym, a chip startup, announced on Monday that it has secured $75 million this year as part of a total funding of $180 million aimed at developing networking chips for artificial intelligence computing in data centers.

Retym produces chips that carry out digital signal processing (DSP) to facilitate rapid information transfer between large data centers—an ability that has gained importance amid the rising interest in AI.

It takes thousands of interconnected chips along with networking equipment to create the foundational AI models that drive applications such as ChatGPT.

Currently, Marvell Technology (MRVL.O) dominates the market for the DSP chips that Retym is developing.

According to report, the Retym chip (pronounced “re-time”) will assist in resolving a bottleneck that has arisen in data centers. Due to the necessity for vast quantities of chips to collaborate on AI computing tasks, their interconnectivity is becoming more critical.

“We are focusing on building coherent DSP chips for the next generation deployment of AI infrastructure and cloud,” report said.

The initial chip from Retym will be crafted for data transfer over distances between 10 and 120 kilometers, with an optimization focus on the 30 to 40 kilometer range. Retym is constructing a DSP chip that employs a modulation technique to guarantee the integrity of transported data.

Navin Chaddha, managing partner at Mayfield (a venture fund that has invested in Retym), stated, “They took the approach of solving the harder problem with longer distances.”

Retym is utilizing Taiwan Semiconductor Manufacturing Co.’s (2330.TW) five-nanometer manufacturing process for the first chip, and its engineers are in the process of testing and validating samples.
