BCM8706 Reference Design
The BCM8706 incorporates a receive equalizer that supports Electronic
Dispersion Compensation (EDC) over multimode fiber (MMF). The
EDC equalizer is designed for applications over MMF covering
distances up to 220m of OM1, OM2, OM3 fiber as per the IEEE
standard. The BCM8706 will be fully compliant with the IEEE802.3aq
standard. In enhanced performance mode, the BCM8706 is capable of
supporting up to 300m over OM1, OM2, and OM3 fiber.
PMD and XAUI clock recovery is performed on the device by
synchronizing directly to the respective incoming data streams. An
external 25-MHz or 156.25-MHz oscillator is required for the reference
clock input.
The BCM8706 Ethernet LRM PHY is a fully integrated SerDes (10.3125
Gbps) interface device performing the extension functions for a 10-GbE
Reconciliation Sublayer (RS) interface. The XGXS, PCS, and PMA
functions include 8B/10B coding, 64B/66B coding, SerDes, Clock
Multiplication Unit (CMU), and Clock and Data Recovery (CDR).
An onboard microcontroller implements the control algorithm for the
MMF EDC DSP Core.
On-chip clock synthesis is performed by the high-frequency low-jitter
phase-locked loops for the PMD and XAUI output retimers. Individual
The BCM8706 is available in a 13 mm × 13 mm, 256-pin FBGA, RoHS
compliant package.
