Description

The UCC5342 IrDA (Infrared Data Association) Transceiver supports the analog section of the IrDA standard. The receiver has a limiting transresistance amplifier to detect a current signal from a PIN diode and drives RXX pulses to a UART. The amplifier is capable of input currents ranging from 200nA to 50mA. The amplifier is bandpass limited to reduce interference from other IR sources.

The output of the receiver is designed to drive CMOS and TTL levels, for direct interfacing to IrDA compliant UARTs and Super I/O devices. Internal resistors are provided for decoupling the detector diode supply, thus minimizing the number of external components required.

The transmitter portion of the chip has a low impedance open drain MOSFET output. It is capable of sinking 300mA from an output LED at 3V, and 500mA at 5V.
