SLLA300–February 2010
FlatLink™ Data Transmission System Using
SN75LVDS83B/SN75LVDS82/SN75LVDS86A
Ankur Verma ......................................................................................... HPA-ICP-High Speed Interface
ABSTRACT
This application report presents various system designs possible using the FlatLink™ transmitter:
SN75LVDS83B, and the FlatLink™ receivers: SN75LVDS82 and SN75LVDS86A. These are low-voltage
differential signaling (LVDS) serializer/deserializer (SerDes) devices commonly used to transmit video data
to liquid crystal display (LCD) panels. The application report starts with an introduction of the FlatLink™
system, followed by the input and output data timing diagrams, and then finally shows different system
designs with the help of system diagrams.
