DESCRIPTION
The DS90C031B is a quad CMOS differential line
driver designed for applications requiring ultra low
power dissipation and high data rates. The device
supports data rates in excess of 155.5 Mbps (77.7
MHz) and uses Low Voltage Differential Signaling
(LVDS) technology.
The DS90C031B accepts TTL/CMOS input levels and
translates them to low voltage (350 mV) differential
output signals. 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
impedance LVDS outputs. This feature assures
minimal loading effect on the LVDS bus lines when
V_CC is not present.
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.
