BCM87580A0KFEBG

Overview

The Broadcom® BCM87580 is a single-chip, low-power, low-latency PAM-4

PHY with integrated retimer and equalizer capabilities to support 400GbE,

2 × 200GbE, 4 × 100GbE, and 8 × 50GbE applications. In these modes, the

BCM87580 retimes, adds FEC (optional), and equalizes n × 50G PAM4 host-side signals to n × 50G PAM-4 line-side signals, driving optical PAM-4 links within next-generation modules, including QSFPDD

and OSFP modules.

The BCM87580 complies with the IEEE 400G AUI-C2M and 200G AUIC2M standards with KP4 FEC and FEC bypass capabilities.

The BCM87580 also supports 1 × 200GbE, 2 × 100GbE, 4 × 50GbE, and 8 × 25GbE modes. In these modes, the device retimes and equalizes incoming data from the host and line sides at n × 25G NRZ rates.

On-chip clock synthesis is performed by a low-cost 156.25 MHz reference clock using a high-frequency, low-jitter phase-locked loop (PLL).

The BCM87580 is fabricated in advanced, low-power 7-nm CMOS technology.

The BCM87580 is available in a 12.5 mm × 11 mm, 0.5 mm pitch, 504-ball BGA, RoHS-compliant package.
