PI90LV3810/PI90LVR3810
High-Speed Differential
Line Receivers
Features
Description
• Ten line receivers meet or exceed the requirements of the
ThePI90LVx3810familyconsistsof tendifferentiallinereceivers
with3-stateoutputsthatimplementLow-VoltageDifferentialSig-
naling (LVDS). The PI90LVR3810 has integrated edge-triggered
D-type flops. Any of the differential receivers will provide a valid
logicaloutputstatewitha±100mVdifferentialinputvoltagewithin
theinputcommon-modevoltagerangethatallows0to3Vofground
potentialdifferencebetweentwoLVDSnodes.TheindependentEN
pins can be used to place the outputs in either a normal logic state
(high or low logic levels) or a high-impedance state. In high-
impedance state, outputs neither load nor drive the bus lines.
ANSITIA/EIA-644-1995Standard
• Designed for signaling rates up to 660 Mbps
• 0V to 3V common-mode input voltage range
• Operates from a single 3.3V supply
• Typical propagation delay time: 2.6ns
• Output skew 100ps (typical)
• Part-to-part skew is less than 1ns
• PI90LVR3810
The intended application of these devices, and their signaling
techniques, is for point-to-point baseband data transmission over
controlledimpedancemediaofapproximately100-Ohmswitha100-
Ohm termination resistor. The transmission media may be printed
circuit board traces, backplanes, or cables. The PI90LV3810’s 10
receivers integrated into the same substrate allow precise timing
alignment. In addition, the PI90LVR3810's integrated registers
resynchronize the data to the system clock, for additional signal
deskew.
Set up time: typical 1ns
Max. clock to output: 1ns
• Integrated110-ohmterminationonPI90LVT386
• LowVoltageTTL(LVTTL)levelsare5Vtolerant
• Open-circuitfailsafe
• Flow-through pin out
• Packaging:
48-Pin Thin Shrink Small Output TSSOP (A)
TheintegratedregistersinthePI90LVR3810areparticularlysuitable
forinterfacingwithLVDSdriverssuchasthePI90LV3811overlong
distances where signal-to-signal skew may be a problem. On the
positive transition of the differential clock (CLK±) input, the Q
outputs of the flip-flop take on the logic levels set up at the
differentialdata(RIN±)inputs.
PI90LV3810
Old data can be retained or new data can be entered while the
outputs are in the high-impedance state. The EN pins do not affect
the internal operation of the flip-flops.
