The BCM8710 is a fully integrated 10GE transmitter operating
at 10.3125 Gbps with serializer and CMU. 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
