Overview
The DS90LV048A device, produced by Texas Instruments (originally developed by National Semiconductor), is a quad CMOS flow-through differential line receiver. It is designed for applications requiring ultra-low power dissipation and high data rates. The device supports data rates in excess of 400 Mbps (200 MHz) using Low Voltage Differential Signaling (LVDS) technology. It translates low voltage differential input signals to 3-V CMOS output levels and features a flow-through pinout that simplifies PCB layout.
