Application Scenarios & Design Considerations

HSDL-3220-021 · 4Mbit/s (FIR) Transceiver Module

Alternative Part Number

  • TFDU4101 --: IR transceiver module in the same IrDA data-rate class with similar footprint and UART interface, widely used as a drop-in replacement for Agilent/Avago HSDL modules.
  • TFBS4711 --: Compact IrDA transceiver with comparable 115.2 kbit/s to 4 Mbit/s capability and low-profile package, suitable substitute when layout is adjusted.
  • ZHX1010 --: IrDA-compliant infrared transceiver offering similar serial interface and data rates, usable as an alternative with minor board rework.
