DS90C031

LVDS Quad CMOS Differential Line Driver

General Description

The DS90C031 is a quad CMOS differential line driver de-

signed for applications requiring ultra low power dissipation

and high data rates. The device is designed to support data

rates in excess of 155.5 Mbps (77.7 MHz) utilizing Low Volt-

age Differential Signaling (LVDS) technology.

The DS90C031 accepts TTL/CMOS input levels and trans-

lates them to low voltage (350 mV) differential output sig-

nals. In addition the driver supports a TRI-STATE® function

that may be used to disable the output stage, disabling the

load current, and thus dropping the device to an ultra low idle

power state of 11 mW typical.

The DS90C031 and companion line receiver (DS90C032)

provide a new alternative to high power psuedo-ECL devices

for high speed point-to-point interface applications.
