Overview
The DS90LT012ATMFX/NOPB is a single-channel, low-voltage differential signaling (LVDS) line receiver manufactured by Texas Instruments. This device is designed to operate from a single power supply with a nominal voltage of 3.3 V, but it can range from 2.7 V to 3.6 V. It is compatible with the ANSI TIA/EIA-644-A standard and supports high-speed data transmission rates up to 400 Mbps (200 MHz). The receiver translates differential input signals into 3-V CMOS output levels, making it suitable for various high-speed interface applications.
