DS90C031B
LVDS Quad CMOS Differential Line Driver
General Description
The DS90C031B is a quad CMOS differential line driver
designed for applications requiring ultra low power dissipa-
tion and high data rates. The device is designed to support
data rates in excess of 155.5 Mbps (77.7 MHz) utilizing Low
Voltage Differential Signaling (LVDS) technology.
The DS90C031B 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.
In addition, the DS90C031B provides power-off high imped-
ance LVDS outputs. This feature assures minimal loading
effect on the LVDS bus lines when V
The DS90C031B and companion line receiver (DS90C032B)
provide a new alternative to high power pseudo-ECL devices
for high speed point-to-point interface applications.
