• Manufacturer Part Number: BCM8125
• Description: 10 GBPS 1:16 DEMUX
• Manufacturer: Broadcom Corporation

The BCM8125 is a fully integrated MSA-compatible quad-rate SONET/
SDH/10GE receiver operating at OC-192/STM-64, 10GE, and two
different FEC (Forward Error Correction) data rates (9.953, 10.3125,
10.664, and 10.709 Gbps) with deserializer, clock and data recovery
(CDR), and loss-of-signal (LOS) detection circuitry. The BCM8125
provides high-jitter tolerance and low-jitter generation to comply with
Optical Internetworking Forum (OIF), IEEE 802.3ae, Telcordia, ANSI,
and ITU-T standards.

The BCM8125 reference clock input frequency is user-selectable to the
line rate divided by either 16 or 64. The reference clock output and the
LVDS receive parallel bus output can be squelched under user control.
An integrated limiting amplifier provides the BCM8125 with input
sensitivity down to 10 mV single ended, saving the customer cost and
power.
The BCM8125 can be powered with a single 1.8V supply or dual 1.8/
3.3V supply without any special power supply sequencing requirements.
The BCM8125 comes in an 11 x 11 mm, 127-pin BGA package.
