‰ Packaging options:
The UT54LVDSC032 Quad Receiver is a quad CMOS
differential line receiver designed 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 Voltage Differential Signaling (LVDS)
technology.
The UT54LVDSC032 accepts low voltage (340mV) differential
input signals and translates them to 5V TTL output levels. The
receiver supports a three-state function that may be used to
multiplex outputs. The receiver also supports OPEN, shorted
and terminated (100 ) input fail-safe. Receiver output will be
HIGH for all fail-safe conditions.
The UT54LVDSC032 and companion quad line driver
UT54LVDS031 provides new alternatives to high power
pseudo-ECL devices for high speed point-to-point interface
applications.

APPLICATIONS INFORMATION
The UT54LVDSC032 receiver’s intended use is primarily in an
uncomplicated point-to-point configuration as is shown in
Figure 3. This configuration provides a clean signaling
environment for quick edge rates of the drivers. The receiver is
connected to the driver through a balanced media which may
be a standard twisted pair cable, a parallel pair cable, or simply
PCB traces. Typically, the characteristic impedance of the
media is in the range of 100. A termination resistor of 100
should be selected to match the media and is located as close to
the receiver input pins as possible. The termination resistor
converts the current sourced by the driver into voltages that are
detected by the receiver. Other configurations are possible such
as a multi-receiver configuration, but the effects of a mid-stream
connector(s), cable stub(s), and other impedance
discontinuities, as well as ground shifting, noise margin limits,
and total termination loading must be taken into account.

The UT54LVDSC032 differential line receiver is capable of
detecting signals as low as 100mV, over a + 1V common-mode
range centered around +1.2V. This is related to the driver offset
voltage which is typically +1.2V. The driven signal is centered
