Product Overview

The TFBS4711-TT1 is a low profile Serial Infrared Transceiver (SIR) module supports IrDA® data rates up to 115.2kbps (SIR). The transceiver module consists of a PIN photodiode, an infrared emitter (IRED) and a low-power CMOS control IC to provide a total front-end solution in a single package. The device is designed for the low power IrDA standard with an extended range on-axis up to 1m. The RXD output pulse width is independent of the optical input pulse width and stays always at a fixed pulse width thus making the device optimum for standard Endecs. It has a tri-state output and is floating in shut-down mode with a weak pull-up. The shutdown (SD) feature cuts current consumption to typically 10nA.
  • Compliant with the latest IrDA physical layer low power specification (9.6 to 115.2kbps)
  • Typical link distance on-axis up to 1m
  • Remote control - transmit distance up to 8m
  • Tri-state receiver output, floating in shutdown with a weak pull-up
  • Constant RXD output pulse width (2.2µs typical)
  • Meets IrFM fast connection requirements
  • Split/independent/unregulated power supply for IRED anode and a well regulated supply for VCC
  • Directly interfaces with various super I/O and controller devices and encoder/decoder
