3.3V LVDS High-Speed Differential Line Drivers and Receivers
ProductFeatures
ProductDescription
• SignalingRates >660Mbps(330MHz)
• Single3.3VPowerSupplyDesign
ThePI90LV179,PI90LV180,PI90LV050,andPI90LV051aredifferen-
tial line drivers and receivers (transceivers) that are compliant with
theIEEE1596.3SCIandANSI/TIA/EIA-644LVDSstandards.These
devices use low-voltage differential signaling (LVDS) to achieve
dataratesinexcessof660Mbpswhilebeinglesssusceptibletonoise
than single-ended transmission.
• Driver:
— ±350mVDifferentialSwingintoa100-Ohmload
— Propogation Delay of 1.5ns Typ.
— LowVoltageTTL(LVTTL)Inputsare5VTolerant
The drivers translate a low-voltage TTL/CMOS input into a low-
voltage (350mV typical) differential output signal. The receivers
translateadifferential350mVinputsignaltoa3VCMOSoutputlevel.
The driver section can be independently set to a power-down and
— Driver is High Impedance when Disabled or V <1.5V

• Receiver:
— Accepts±50mV(min.)DifferentialSwingwithupto2.0V
ground potential difference
— Propagation Delay of 3.3ns Typ.
— LowVoltageTTL(LVTTL)Outputs
— Open, Short, and Terminated Fail Safe
high-impedance output mode with the D pin (active HIGH). The
EN
receiver section is controlled by the R
pin (active LOW).

• PackageOptions:SOIC,TSSOP,MSOP
Applications
Applications include point-to-point and multidrop baseband data
transmission over a controlled impedance media of approximately
100 ohms. These include intra-system connections via printed
circuit board traces or cables, hubs and routers for data communi-
cations;PBXs,switches,repeatersandbasestationsfortelecommu-
nications and other applications such as digital cameras, printers
and copiers.
