BCM8109:Multirate 10-Gbps SONET/SDH/10GE/FC/FEC Demultiplexer
The BCM8109 is a fully integrated MSA-compliant multirate SONET/ SDH/10GE/FC/FEC receiver operating at OC-192 (9.953 Gbps), 10GE (10.3125 Gbps), 10GFC (10.315 Gbps), or different FEC (Forward ErrorCorrection) data rates (10.664/10.709, 11.096, or 11.31 Gbps). The BCM8109 provides deserializer, clock and data recovery (CDR), and
loss-of-signal (LOS) detection circuitry and an advanced feature set that includes phase adjustment and adaptive decision threshold adjustment. The BCM8109 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 BCM8109 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.

The BCM8109 can be powered with a single 1.2V supply or dual 1.2/3.3V supply without any special power supply sequencing requirements.The BCM8109 is a register-based device; settings can be controlled via the Broadcom Serial Control (BSC) interface.
The BCM8109 comes in a 15 mm x 15 mm, 143-pin BGA package.
