FIN1028

3.3V LVDS 2-Bit High Speed Differential Receiver

General Description

This dual receiver is designed for high speed interconnects

utilizing Low Voltage Differential Signaling (LVDS) technol-

ogy. The receiver translates LVDS levels, with a typical dif-

ferential input threshold of 100 mV, to LVTTL signal levels.

LVDS provides low EMI at ultra low power dissipation even

at high frequencies. This device is ideal for high speed

transfer of clock and data.

The FIN1028 can be paired with its companion driver, the

FIN1027, or any other LVDS driver.
