Overview
The SN65LVDS93DGG is a Low-Voltage Differential Signaling (LVDS) serializer/deserializer (SerDes) transmitter produced by Texas Instruments. This integrated circuit contains four 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer, and five LVDS drivers. It enables the synchronous transmission of 28 bits of single-ended LVTTL data over five balanced-pair conductors, making it suitable for point-to-point subsystem communication with very low Electromagnetic Interference (EMI).
