The low-jitter LVDS interface and the onboard low-jitter phase-locked loop (PLL) meets Optical Internetworking Forum (OIF), IEEE 802.3ae, Telcordia, ANSI, and ITU-T jitter standards. The BCM8710 reference clock input frequency is user-selectable to the line rate divided by either 16 or 64. A 10-word FIFO decouples the parallel input timing domain from the serial output timing domain. The BCM8710 provides a CML serial output clock to retime the data at the optical interface. Major transmitter functions are: * 16-bit, LVDS parallel input * Elastic buffering FIFO with overflow indicator * 10.3125-GHz CMU * 10.3125-Gbps CML transmit serial data output * Parallel-to-serial conversion * Selectable reference clock frequency * Lock detect Broadcom(R), the pulse logo(R) and Connecting EverythingTM are trademarks of Broadcom Corporation and/or its subsidiaries in the United States and certain other countries.
