Overview
The SN65LVDS93 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 (Low-Voltage Transistor-Transistor Logic) data over five balanced-pair conductors to a compatible receiver, such as the SN65LVDS94.
The device operates from a single 3.3-V supply, consumes 250 mW typically, and is characterized for operation over an ambient air temperature range of -40°C to 85°C. It is packaged in a Thin Shrink Small-Outline Package (TSSOP) with 56 pins and a 20 mil terminal pitch.
