Description

The UCC5343 IrDA Transceiver with Encoder/Decoder supports the Physical Layer specifications of the IrDA standard. Additional functionality is provided by data format translation between standard UART and IrDA formats. The UCC5343 is readily interfaced to a standard UART.

The Receiver has a limiting transresistance amplifier to detect a current signal from a PIN diode and drives RXX pulses into a UART. The receiver 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.

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.

The UCC5343 has low current consumption in the active mode, making it excellent for applications with low power requirements. The transmitter section has a low impedance open drain MOSFET output. It is capable of sinking 300mA from an output LED at 3V and 500mA at LED at 5V.
