BCM81356 16-nm 16 x 56 Gb/s PAM-4 Duplex PHY Data Sheet Overview The Broadcom® BCM81356 is a single-chip 16 × 56 Gb/s full-duplex PHY.

It supports both the PAM-4 and NRZ data formats.

It supports various operation modes, such as Retimer, Forward, and Reverse Gearbox modes.

It also supports 10G, 25G, 40G, 50G, 100G, 200G, and 400G linecard applications.

On-chip clock synthesis is performed by a low-cost reference clock through high-frequency, low-jitter phaselocked loops (PLLs).
