BCM8109

Description

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 Error Correction) 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.
