Overview
The DS90LV028A, produced by Texas Instruments, is a dual CMOS differential line receiver designed 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 exceeding 400 Mbps (200 MHz). It translates low voltage differential input signals to 3-V CMOS output levels, making it an efficient alternative to high power PECL/ECL devices for high-speed point-to-point interface applications.
