Product Description

The PI90LV179is a differential line driver and receiver (transceiver) that is compliant with the IEEE 1596.3 SCI and ANSI/TIA/EIA-644 LVDS standards. This device uses low-voltage differential signaling (LVDS) to achieve data rates in excess of 660 Mbps while being less susceptible to noise than single-ended transmission.

The driver translates a low-voltage TTL/CMOS input into a lowvoltage (350mV typical) differential output signal. The receiver translates a differential 350mV input signal to a 3V CMOS output level.


  • Signaling Rates >660 Mbps (330 MHz)
  • Single 3.3V Power Supply Design
  • Driver:
    • ±350mV Differential Swing into a 100-ohm load
    • Propogation Delay of 1.5ns Typ.
    • Low Voltage TTL (LVTTL) Inputs are 5V Tolerant
  • Receiver:
    • Accepts ±50mV (min.) Differential Swing with up to 2.0V ground potential difference
    • Propagation Delay of 3.3ns Typ.
    • Low Voltage TTL (LVTTL) Outputs
    • Open, Short, and Terminated Fail Safe
  • Industrial Temperature Operating Range: –40°C to 85°C
  • Meets or Exceeds IEEE 1596.3 SCI Standard
  • Meets or Exceeds ANSI/TIA/EIA-644 LVDS Standard
  • Bus-Terminal ESD exceeds 12kV
  • Packaging (Pb-free & Green available):
    • 8-pin SOIC or MSOP


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 communications; PBXs, switches, repeaters and base stations for telecommunications and other applications such as digital cameras, printers and copiers.
