Transmit Serializer
The Transmit Serializer blocks, TWPS and TPPS, convert 8B/10B characters to bit-serial format.
The Transmit Working Serializer, TWPS, generates a serial stream for the working transmit
LVDS link, TPWRK/TNWRK. The Transmit Protect Serializer, TPPS, generates a serial stream
for the protect transmit LVDS link, TPPROT/TNPROT.
The LVDS Transmitters, TWLV and TPLV, convert 8B/10B encoded digital bit-serial streams to
LVDS signaling levels. The Transmit Working LVDS Interface, TWLV, drives the working
transmit LVDS links, TPWRK/TNWRK. The Transmit Protect LVDS Interface block, TPLV,
drives the protect transmit LVDS link, TPPROT/TNPROT.
The Clock Synthesis Unit (CSU) block generates the 777.6 MHz clock for the transmit and
receive LVDS links.
The Transmit Voltage Reference Generator block generates bias voltages and currents for the
LVDS Transmitters.
