Overview
The SN65LVDS93B-Q1 is a versatile transmitter designed by Texas Instruments for the synchronous transmission of 28 bits of single-ended LVTTL (Low-Voltage Transistor-Transistor Logic) data over five balanced-pair conductors using Low-Voltage Differential Signaling (LVDS). This integrated circuit contains four 7-bit parallel-load serial-out shift registers, a 7X clock synthesizer, and five LVDS line drivers. It is optimized for automotive display applications, including navigation, cluster displays, and center stack displays, and operates over a temperature range of –40°C to 85°C.
