FIN1048
3.3V LVDS 4-Bit Flow-Through
High Speed Differential Receiver
General Description
This quad receiver is designed for high speed interconnect
utilizing Low Voltage Differential Signaling (LVDS) technol-
ogy. The receiver translates LVDS levels, with a typical dif-
ferential input threshold of 100mV, 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 FIN1048 can be paired with its companion driver, the
FIN1047, or any other LVDS driver.
