UCC5343  
PRELIMINARY  
IrDA Transceiver with Encoder/Decoder  
FEATURES  
DESCRIPTION  
Micropower in the Sleep Mode, (2µA)  
The UCC5343 IrDA Transceiver with Encoder/Decoder supports the  
Physical Layer specifications of the IrDA standard. Additional functional-  
ity is provided by data format translation between standard UART and  
IrDA formats. The UCC5343 is readily interfaced to a standard UART.  
3V to 5V Operation  
Wide Dynamic Receiver Range from  
200nA to 50mA Typical  
The Receiver has a limiting transresistance amplifier to detect a current  
signal from a PIN diode and drives RXX pulses into a UART. The re-  
ceiver is capable of detecting input currents ranging from 200nA to  
greater than 50mA. The receiver signal path is frequency limited by an  
internal bandpass filter to reduce interference from other sources of IR  
energy.  
Direct Interface to IrDA Compatible  
UARTs or Super I/O ICs  
Supports IrDA Standard to 115.2kbps  
Data Rates  
Transmitter Output Stage Capable to  
500mA Sink Current  
The output of the receiver is designed for direct interface to standard  
UARTs and Super I/O devices up to 115.2kbps. Internal resistors are  
provided for decoupling the pin diode supply, minimizing the number of  
required external components.  
IrDA Compliant Modulation &  
Demodulation Scheme  
The UCC5343 has low current consumption in the active mode, making  
it excellent for applications with low power requirements. The transmit-  
ter section has a low impedance open drain MOSFET output. It is capa-  
ble of sinking 300mA from an output LED at 3V and 500mA at LED at  
5V.
