Description

The BCM8128 is a fully integrated metro, long-haul, ultra long-haul transmitter operating at OC-192, 10GE, and two FEC (Forward Error Correction) data rates (9.953, 10.3125, and 10.664/10.709 Gbps, respectively) with serializer and Clock Multiplication Unit (CMU). The BCM8128 interface and onboard low-jitter PLL exceed Optical Internetworking Forum (OIF), IEEE 802.3ae, Telcordia, ANSI, and ITU-T jitter standards.

The BCM8128 reference clock input frequency is user-selectable to the line rate divided by either 16 or 64. The two reference clock outputs can be squelched under user control. The BCM8128 provides skew control between the LVDS transmit parallel input clock and data to accommodate difficult timing variances.
