Compliant with industry standards such as Optical
Internetworking Forum (OIF), Telcordia, ANSI, IEEE
802.3ae, and ITU-T specifications.
Reduces design cycle and time to market.
Low power consumption eliminates an external heat
sink on the chip and fans for system airflow.
High level of integration allows for higher port density
solutions.
CMOS-based device takes advantage of the most
effective silicon economy of scale.
Target applications:
Transmission equipment
Optical modules and test equipment
ADD/DROP multiplexers
Digital cross-connects
ATM switch backbones
Terabit routers
Edge routers
Hubs and repeaters
Network interface card (NIC)

The BCM8111 is a fully integrated SONET/SDH receiver
operating at the OC-192/STM-64 data rate of 9.953 Gbps with
deserializer, Clock and Data Recovery (CDR), and Loss-of-
Signal (LOS) detection circuitry.
The BCM8111 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 BCM8111 reference clock frequency is user-selectable to
either the line rate divided by 16 or the line rate divided by 64.
The BCM8111 receiver implements receive functions for
SONET/SDH 10-Gbps equipment. The major functions of the
chip are:
9.95328-GHz CDR
CML Receive Serial Data input
16-bit parallel LVDS output
Selectable reference clock frequencies
Serial-to-parallel conversion
Lock detect
