BCM8073

Description

The BCM8073 is a dual-channel 10-GbE serial transceiver targeting the new IEEE 10GBASE-KR standard for running 10G serial data over backplane systems. The BCM8073 incorporates sophisticated receive equalizers, which extend the life of legacy systems currently running at 1G or XAUI data rates by providing a 4x or 10x bandwidth improvement on each channel.

On-chip clock synthesis of BCM8073 is performed by the high-frequency, low-jitter phase-locked loops (PLL) for the PMD and XAUI output retimers. Individual PMD and XAUI clock recovery is performed on the device by synchronizing directly with the respective incoming data streams. An external 25-MHz or 156.25-MHz oscillator is required for the reference clock input.
