Overview
The DS90LV028A, produced by Texas Instruments, is a dual CMOS differential line receiver designed for applications that require 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 and is compatible with existing 5-V LVDS networks. The DS90LV028A features a flow-through pinout, which simplifies PCB layout, and includes fail-safe protection for open, shorted, or terminated input conditions.
