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. Figure 2 and Figure 3 illustrate the block diagrams of the QuickSD device transmitter and receiver.
