BCM8705 Fully Integrated Interface
The BCM8705 Ethernet/Fibre Channel/SONET LAN/WAN PHY is a
fully integrated serialization/deserialization (9.953/10.3125/
10.5188-Gbps) interface device performing the extension functions for a
10-gigabit serial Ethernet reconciliation sublayer (RS) interface. The
XGXS, PCS, and PMA functions include 8B/10B coding, 64B/66B
coding, SerDes, WIS, clock multiplication unit (CMU), and clock and
data recovery (CDR).
For WAN applications, a WIS-compliant framer with flexible clocking
modes allows transmission of Ethernet traffic over a WAN network.
On-chip clock synthesis is performed by the high-frequency low-jitter
phase-locked loops for the PMD and XAUI output retimers. Individual
PMD and XAUI clock recovery is performed on the device by
synchronizing directly to their respective incoming data streams. Elastic
buffers are provided to allow the XAUI and PMD interfaces to operate
in asynchronous configuration. Only an external 155.52/156.25/
159.38-MHz oscillator is required for the reference clock input.
The BCM8705 is available in a 13-mm × 13-mm, 256-pin FBGA with a
0.8-mm ball pitch and also in a 17-mm x 17-mm, 256-pin 1-mm ball
pitch RoHS-compliant package.
