The Broadcom
BCM5500
is a fully integrated Quad transceiver
housed in a plastic BGA package. Manufactured in a standard
single-poly low-cost CMOS process, the chip provides
aggregate bandwidth for serial transfer of raw data at 10 Gbps.
The chip also provides a physical layer solution of 1.25 to 3.125
Giga Baud (GB) data transfer per channel, and is the world’s
lowest power per channel transceiver (250 mW).
Fully integrated PLL and CDR enables individual channels
to lock to the incoming data. The unique design of the VCO
and CDR blocks have resulted in the world’s lowest jitter
PLL (ULJ).

All receivers can be synchronized using a robust buffer design.
Similarly, the chip offers the option of synchronizing the
transmitters for simultaneous transmission. The transmitter
section accepts 10-bit wide (TBI) parallel LVTTL/SSTL_2
data at 125 MHz byte clock and serializes into LVPECL high
speed serial data for each channel. The receiver section
enables individual channels to lock to the incoming data. The
recovered data is presented at LVTTL/SSTL_2 parallel
outputs. The 8B/10B encoding and 10B/8B decoding of the
PCS layer, speed selection, alignment schemes, VCO and
Synch, and bypass capabilities are addressed through
configuration registers.
