The AS1152 is a Quad Flow-Through LVDS (Low-VoltageDifferenTIal Signaling) Line Driver which acceptsand converts LVTTL/LVCMOS input levels into LVDSoutput signals. The device is perfect for low-power lownoiseapplicaTIons requiring high signaling rates andreduced EMI emissions.The device is guaranteed to transmit data at speeds upto 500Mbps (250MHz) over controlled impedance mediaof approximately 100Ω. Supported transmission mediaare PCB traces, backplanes, and cables.The AS1152 is capable of setTIng all four outputs to ahigh-impedance state through two Enable Inputs (ENand ENn – internally pulled down to GND), dropping thedevice to an ultra-low-power state of 16mW (typical) duringhigh impedance. The Enable Inputs are common toall four drivers.Outputs conform to the ANSI TIA/EIA-644 LVDS standards.Flow-through pinout simplifies PC board layoutand reduces crosstalk by separating the LVTTL/LVCMOSinputs and LVDS outputs.The AS1152 operates from a single +3.3V supply and isspecified for operation from -40 to +85°C.
