General Description
LVDS SERDES Transmitter and Receiver
A QuickSD LVDS SERDES device in serializer mode takes a parallel data bus and a separate
clock and converts them into a serial data stream. In deserializer mode, it takes a serial data
stream and converts it to a configurable bit wide parallel data bus and separate clock. The
reduced number of I/O board traces and cable connectors saves on cost and significantly
simplifies design. Skew and timing issues are significantly reduced and performance is
enhanced.

transmitter and receiver.
