Broadcom Releases 7nm 800G PAM-4 PHY Devices for Data Center, Cloud and AI

Broadcom

Broadcom (NASDAQ: AVGO) has expanded its portfolio with the launch of “high-performance” 7nm 800G PAM-4 PHY devices for data center, cloud and AI networks. The portfolio includes a new family of 800G optical PHY devices, the BCM8780X, optimized for QSFP-DD800 and OSFP transceiver module applications. It also includes an 800G 8:8 retimer PHY device, the BCM87360, designed for line card applications.

“Continuing Broadcom’s strategy of building best-in-class PHYs, the two new 8x100G PHY families being sampled today expands our industry leading 7nm PAM4 product line,” said Lorenzo Longo, Broadcom.

Using 7nm process technology from the Centenario PHY platform shipping in production, these new 8x100G PHYs would provide high performance along with low power per bit.

Combined with Broadcom’s 100G single-lambda optics for both MMF and SMF fiber optics and 25.6T switch that integrates 100G I/Os, this new PHY portfolio would complete all the critical blocks needed for data center and cloud providers to develop and build out their 800G infrastructure networks.

“The data center industry has begun gearing up for 800G optical connectivity in 2020,” said Dr. Vladimir Kozlov, CEO and founder of LightCounting Market Research. “Broadcom is the driving force behind it, offering switching ICs, optics and now PHY chips designed for 25.6T 1RU switches with 32 of 800G optical ports. It’s certain that one major hyperscaler will be using these products next year and other cloud companies may be adding it to their plans.”

100G and 400G

As 5G and AI become more prevalent, coupled with recent upward trends in video conferencing and live streaming, data center providers and cloud companies will need more network bandwidth to keep up with data demands, according to Broadcom.

100G and 400G deployments are ramping across data center and cloud networks while global data demands continue to rise with advances in technology, stated the vendor. 800G is the next evolution in high-speed optical connectivity. It would be essential in meeting bandwidth needs by enabling ultra-high-density network equipment.

The BCM8780X optical PHY and the BCM87360 retimer PHY solutions would ensure a smooth migration to new network architectures.

“Continuing Broadcom’s strategy of building best-in-class PHYs, the two new 8x100G PHY families being sampled today expands our industry leading 7nm PAM4 product line,” said Lorenzo Longo, senior vice president and general manager of the Physical Layer Products Division at Broadcom. Broadcom provides optimized solutions for a wide range of optical and line card applications at both 50G and 100G. No other company offers the same portfolio breadth with an equivalent level of investment and IP availability to enable the next level of network expansion.”
