Broadcom recently announced a family of 800-gigabit physical layer (PHY) chips. The device family is the company’s first 800-gigabit ICs with 100-gigabit input-output (I/O) interfaces.
Moving from 50-gigabit to 100-gigabit-based I/O enables a new generation of 800-gigabit modules aligned with the latest switch chips.
“With the switch chip having 100-gigabit I/Os, PHYs are needed with the same interfaces,” says Machhi Khushrow, senior director of marketing, physical layer products division at Broadcom.
Broadcom’s latest 25.6 terabit-per-second (Tbps) Tomahawk 4 switch chip using 100-gigabit I/O was revealed at the same time.
