Printers DESCRIPTION
The SN75LVDT1422 Full Duplex Serializer/Deserializer incorporates a 14-bit serializer and a 14-bit deserializer.
Operation of the serializer is independent of the operation of the deserializer. The 14-bit serializer accepts 14
TTL input lines and generates 2 LVDS high-speed serial streams plus one LVDS clock signal. The 14-bit
deserializer accepts 3 LVDS input signals (2 high-speed serial streams and one LVDS clock signal) and drives
out 14 TTL data signals plus one TTL clock.
The serializer loads 14 data bits into registers upon the rising or falling edge of the input clock signal (CLK IN). …
