PRELIMINARY

IrDA 115.2kbps Transceiver

FEATURES

DESCRIPTION

•

Supports IrDA Standard to 115kbps

Data Rates

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 cur-

rents ranging from 200nA to 50mA. The amplifier is bandpass limited to

reduce interference from other IR sources.

•

3V to 5V Operation

Wide Dynamic Receiver Range from

200nA to 50mA Typical

•

IrDA Compliant I/O

500mA LED Driver

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.

Very Low Quiescent Current in Active

Mode (250µA Typical)

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.

•

Ultra Low Quiescent Current in Sleep

Mode (0.5µA Typical)

Compatible with IrDA Detector Diodes
