Overview
The DS90LV048A, produced by Texas Instruments, is a quad CMOS flow-through differential line receiver designed for applications requiring ultra-low power dissipation and high data rates. This 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, making it suitable for high-speed point-to-point interface applications. The DS90LV048A features a flow-through pinout that simplifies PCB layout and ensures easy matching of electrical lengths of the differential pair trace lines between the driver and the receiver.
