Vishay Pioneers IrDA-Compliant IR Transceiver Module

Vishay Intertechnology

Vishay Intertechnology announced that the company is providing designers with a new device for IrDA-compliant infrared (IR) transceiver modules in the standard 6.8 mm by 2.8 mm by 1.6 mm footprint.

Vishay Semiconductors’ TFBR4650 offers a reliable drop-in replacement for devices from other manufacturers. In cases of discontinuation of competitors’ parts, this drop-in replacement prevents any need for PCB redesigns.

The device introduced by Vishay consists of a PIN photodiode, infrared emitter, and control IC in a single package. Compliant with the latest IrDA physical layer standard for IR data communication, the module supports data rates from 9.6 kbit/s to 115.2 kbit/s (SIR) for wireless transmission in gas and power meters, cell phones, microphones, robots, and mobile medical devices.

The Key Features of the Vishay TFBR4650 include

  • Compliant with the IrDA physical layer IrPHY 1.4 (low power specification, 9.6 kbit/s to 115.2 kbit/s)
  • Link distance: 30 cm / 20 cm full 15° cone with standard or low power IrDA, respectively. Emission intensity can be set by an external resistor to increase the range for extended low power spec to > 50 cm
  • Typical transmission distance to standard device: 50 cm

Samples and production quantities of the new IR transceiver module are available now, with lead times of eight weeks.
