The low-jitter LVDS 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. A 10-word FIFO decouples the parallel input timing domain from the serial output timing domain. The BCM8128 provides a CML serial output clock to retime the data at the optical interface. The BCM8128 can be powered with a single 1.8V supply or dual 1.8/ 3.3V supply without any special power supply sequencing requirements. The BCM8128 comes in a 11 x 11 mm, 127-pin BGA package.
