The BCM8128 is a fully integrated MSA-compliant quad-rate SONET/

SDH/10GE transmitter operating at OC-192 (9.953 Gbps), 10GE

(10.3125 Gbps), 10GFC (10.513 Gbps), and Forward Error Correction

(FEC) data rates (10.664/10.709, 11.096, or 11.31 Gbps) with serializer

and Clock Multiplication Unit (CMU). 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 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 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 comes in a 11 x 11 mm, 127-pin BGA package.
