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.
