The AS1150 and AS1151 are quad flow-through LVDS(low-voltage differenTIal signaling) receivers whichaccept LVDS differenTIal inputs and convert them toLVCMOS outputs. The receivers are perfect for lowpowerlow-noise applicaTIons requiring high signalingrates and reduced EMI emissions.The devices are guaranteed to receive data at speedsup to 500Mbps (250MHz) over controlled impedancemedia of approximately 100Ω. Supported transmissionmedia are PCB traces, backplanes, and cables.The AS1150 uses high impedance inputs and requiresan external terminaTIon resistor when used in a point-topointconnection. The AS1151 features integrated paralleltermination resistors (nominally 107Ω), which eliminatethe requirement for discrete termination resistors,and reduce stub lengths.The integrated failsafe feature sets the output high if theinputs are open, undriven and terminated, or undrivenand shorted. Enable inputs (EN and ENn – internallypulled down to GND) control the high-impedance outputand are common to all four receivers. All inputs conformto the ANSI TIA/EIA- 644 LVDS standards. Flow-throughpinout simplifies PC board layout and reduces crosstalkby separating the LVDS inputs and LVCMOS outputs.The devices are available in a 16-pin TSSOP package.
