BCM87326

BCM87326 7-nm 16 x 56-Gb/s PAM-4 Duplex PHY Preliminary Data Sheet Overview The Broadcom® BCM87326 is a single-chip 16 × 56-Gb/s full-duplex PHY that supports both the PAM-4 and NRZ data formats. It supports various operation modes, such as the Retimer, Forward, and Reverse Gearbox modes. It also supports the 10G, 25G, 40G, 50G, 100G, 200G, and 400G line-card applications. On-chip clock synthesis is performed by a low-cost reference clock through high-frequency, low-jitter phaselocked loops (PLLs). The BCM87326 is fabricated in advanced low-power 7-nm CMOS technology. The BCM87326 is available in a 23 mm × 23 mm, 0.8-mm pitch, 729-ball BGA, RoHS-compliant package.
