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