Broadcom Announces Industry’s First 100G/lane Optical PAM-4 DSP PHYs with Integrated TIA and Laser Driver
09 November 2021 - 5:00AM
Broadcom Inc. (NASDAQ: AVGO) today announced its 100G/lane optical
PAM-4 DSP PHY families with integrated transimpedance amplifier
(TIA) and laser driver, the Jesko BCM8741x and Gemera BCM8781x,
optimized for 400G DR4/FR4 and 800G DR8/2xFR4 module applications,
respectively. Built on Broadcom’s proven 112G PAM-4 DSP platforms,
these highly integrated DSP PHYs provide superior performance with
lower power enabling 7W 400G DR4/FR4 and sub 14W 800G DR8/2xFR4
optical modules.
Solution Highlights
- 400G and 800G DSP PHYs with integrated TIA and high-swing laser
driver deliver best-in-class module performance in BER and power
consumption
- Enables industry’s lowest power 400G and 800G pluggable optical
modules
- Compliant to all applicable IEEE and OIF standards, capable of
supporting MR links on the chip to module interface
- Powers Silicon Photonics (SiPh) as well as discrete EML/PD
based modules
- Drives higher density and bandwidth with hyperscale cloud
networking data centers
“Ever increasing compute density and networking bandwidths
demand unrelenting quest for lower power, cost and form factor
reduction,” said Vijay Janapaty, vice president and general
manager of the Physical Layer Products Division at Broadcom.
“Broadcom’s innovative and highly integrated optical DSPs drive
industry leading optical module solutions that meet the roadmap
needs of our hyperscale cloud customers.”
“Networking and compute advances continue to push the boundaries
of the power, performance and cost of optical modules,”
said Adit Narasimha, vice president and general manager of
Optoelectronics at Molex. “Molex’s PAM-4 optical modules pair the
advantages of Broadcom’s highly integrated DSPs with the high
performance of Molex’s SiPh ICs to deliver extremely low power,
high performance and cost-effective solutions that will serve the
industry’s multi-generational needs.”
“Demand for optical connectivity continues to exceed our
expectations. Several millions of 400G transceivers will be shipped
in 2021 and 800G modules are starting to ship as well,” commented
Dr. Vladimir Kozlov, CEO and founder of LightCounting. “PAM-4 DSPs
account for 50% of power consumption in 400/800G transceivers.
Improvements in power efficiency of these chips are welcomed by
everyone in the industry, the climate scientists and even the G20
leaders, who found common ground on climate policies last
month.”
