Overview
The SN65LVDS93B, produced by Texas Instruments, is a Low-Voltage Differential Signaling (LVDS) SerDes (serializer/deserializer) transmitter. This integrated circuit is designed to facilitate the synchronous transmission of 28 bits of single-ended LVTTL (Low-Voltage Transistor-Transistor Logic) data over five balanced-pair conductors. It integrates four 7-bit parallel load serial-out shift registers, a 7 × clock synthesizer, and five LVDS drivers, enabling efficient data transmission to compatible receivers such as the DS90CR286A and SN65LVDS94.
