DESCRIPTION

The DS90C032B is a quad CMOS differential line

receiver 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 DS90C032B accepts low voltage (350 mV)

differential input signals and translates them to

CMOS (TTL compatible) output levels. The receiver

supports a TRI-STATE function that may be used to

multiplex outputs. The receiver also supports OPEN

Failsafe and terminated (100Ω) input Failsafe with the

addition of external failsafe biasing. Receiver output

will be HIGH for both Failsafe conditions.

The DS90C032B provides power-off high impedance

LVDS inputs. This feature assures minimal loading effect on the LVDS bus lines when VCC is not

present.

The DS90C032B and companion line driver

(DS90C031B) provide a new alternative to high

power pseudo-ECL devices for high-speed point-topoint

interface applications.
