BCM8124

Description

The BCM8124 is a fully integrated MSA-compatible quad-rate SONET/SDH/10GE/FEC transmitter operating at 9.953, 10.3125, 10.664, and 10.709 Gbps with serializer and Clock Multiplication Unit (CMU). The lBCM8128 interface and onboard low-jitter PLL exceed Optical Internetworking Forum (OIF), IEEE 802.3ae, Telcordia, ANSI, and ITU-T jitter standards.

The BCM8124 reference clock input frequency is user-selectable to the line rate divided by either 16 or 64. The BCM8124 provides skew control between the LVDS transmit parallel input clock and data to accommodate difficult timing variances. A 10- word FIFO decouples the parallel input timing domain from the serial output timing domain.
