Overview
The DS90C365AMTX/NOPB is a +3.3V Programmable LVDS (Low Voltage Differential Signaling) Transmitter produced by Texas Instruments. This component is designed for 18-bit flat panel display links and operates at frequencies up to 87.5 MHz. It is pin-to-pin compatible with the DS90C363, DS90C363A, and DS90C365, offering enhanced features and improvements over its predecessors. The DS90C365A converts 21 bits of LVCMOS/LVTTL data into four LVDS data streams, along with a phase-locked transmit clock, making it an ideal solution for high-speed data transmission in display applications.
