BCM82756AIFSBG

The Broadcom BCM82756 is a low-power, high-density PHY that integrates IEEE 802.1AE MACsec GCM-AES-256b encryption, IEEE 1588, retimer, and EDC equalizer functions supporting 1GbE, 10GbE, and 40GbE applications. The BCM82756 is targeted for SMF, MMF, or copper twin-axial applications interfacing to both limiting-based and linear-based SFP+ and SFP modules. The BCM82756 is fully compliant with the 10GbE IEEE 802.3aq standard and also supports 1000BASE-X for 1GbE operation. The BCM82756 is developed using an all-DSP high-speed front end, providing the highest performance and most flexibility for LRM applications. On-chip clock synthesis is performed by a single low-cost 156.25 MHz reference clock (for all IEEE standard 1G/10G rate) via high-frequency, low-jitter, phase-locked loops (PLLs). Individual clock recovery is performed on the device by synchronizing directly to the respective incoming data streams.
