Inphi unveils a second 400G PAM-4 IC family

Inphi has announced the Vega family of 4-level, pulse-amplitude modulation (PAM-4) chips for 400-gigabit interfaces.

The 16nm CMOS Vega IC family is designed for enterprise line cards and is Inphi’s second family of 400-gigabit chips that support eight lanes of 50-gigabit PAM-4.

Its first 8x50-gigabit family, dubbed Polaris, is used within 400-gigabit optical modules and was announced at the OFC show held in Los Angeles in March.

“Polaris is a stripped-down low-power DSP targeted at optical module applications,” says Siddharth Sheth, senior vice president, networking interconnect at Inphi (pictured). “Vega, also eight by 50-gigabits, is aimed at enterprise OEMs for their line-card retimer and gearbox applications.”
