Description
The PI90LV048A/PI90LVT048A quad flow-through differential line
receivers are designed for applications requiring ultra low-power
dissipation and high data rates. The device is designed to support
data rates in excess of 500 Mbps (250 MHz) using Low Voltage
Differential Signaling (LVDS) technology.
The devices accept low-voltage (350 mV typical) differential input
signals and translates them to 3V CMOS output levels. The receiver
supports a 3-state function, which may be used to multiplex outputs,
and also supports open, shorted and terminated (100-ohms) input fail-
safe. The receiver output will be HIGH for all fail-safe conditions.
PI90LVT048A features integrated parallel termination resistors
(nominally 110-ohms) that eliminate the requirement for four dis-
crete termination resistors and reduce stud length. PI90LV048A
inputs are high impedance and require an external termination
resistor when used in a point-to-point connection. The devices
have a flow-through pinout for easy PCB layout.
The EN and EN inputs are ANDed together and control the 3-state
outputs. The enables are common to all four receivers. The
PI90LV048A and companion LVDS line driver (eg. PI90LV047A)
provide a new alternative to high-power PECL/ECL devices for
high-speed point-to-point interface applications.
