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 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.
