PI90LV386/PI90LVT386
High-Speed Differential Line Receivers
Description
Features
• Sixteen line receivers meet or exceed the requirements of the
ThePI90LVx386familyconsistsof sixteendifferentiallinereceivers
with 3-state outputs that implement Low-Voltage Differential
Signaling (LVDS). Any of the differential receivers will provide a
valid logical output state with a ±100mV differential input voltage
withintheinputcommon-modevoltagerangethatallows0to3Vof
groundpotentialdifferencebetweentwoLVDSnodes.Theindepen-
dentENpinscanbeusedtoplacetheoutputsineitheranormallogic
state (high or low logic levels) or a high-impedance state. In high-
impedance state, outputs neither load nor drive the bus lines.
The intended application of these devices, and their signaling
techniques, is for point-to-point baseband data transmission over
controlled impedance media of approximately 100-ohms with a
100-Ohmterminationresistor.ThePI90LVT386integratesthetermi-
nating resistors while the PI90LV386 requires external resistors.
The transmission media may be printed circuit board traces,
backplanes,orcables.ThePI90LV386’s16receiversintegratedinto
the same substrate allow precise timing alignment.

Notes:
1. All typical values are at 25°C and with a 3.3V supply
2. tsk(o) is the magnitude of the time difference between the tPLH or tPHL of all drivers of a single device with all of their inputs connected
together.
3. tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices operate
with the same supply voltages, at the same temperature, and have identical packages and test circuits.
4. ROUT0 disable time is 1 nanosecond greater.
