Overview
The DS90LV028A-Q1 is a dual CMOS differential line receiver designed by Texas Instruments for applications requiring ultra-low power dissipation, low noise, and high data rates. This device utilizes Low Voltage Differential Signaling (LVDS) technology to support data rates in excess of 400 Mbps (200 MHz). It is AEC-Q100 qualified for automotive applications, ensuring reliability over a temperature range of -40°C to +105°C. The receiver accepts low voltage differential input signals and translates them to 3 V CMOS output levels, making it suitable for high-speed point-to-point interface applications.
