Описание трансивера Avago AFBR-57F5PZ

The AFBR-57F5PZ is a multi-rate 850nm transceiver which
ensures compliance with FC-PI-5 16GFC, 8GFC and 4GFC
specifications. Per the requirements of 16GFC, internal
clock and data recovery circuits (CDRs) are present on
both electrical input and electrical output of this transceiver.
These CDRs will lock at 14.025Gb/s (16GFC) but
must be bypassed for operation at 8.5Gb/s (8GFC) and
4.25Gb/s (4GFC), accomplished by using two Rate Select
inputs to configure transmit and receive sides. Transmitter
and receiver can operate at different data rates, as is often
seen during Fibre Channel speed negotiation.

Digital diagnostic monitoring information (DMI) is present
in the AFBR-57F5PZ per the requirements of SFF-8472,
providing real time monitoring information of transceiver
laser, receiver and environment conditions over a SFF-
8431 2-wire serial interface.
