Pin Functions

PIN I/O DESCRIPTION
NAME NO.
16XCLK 1 I Clock signal. 16XCLK must be set to 16 times the baud rate. The highest baud rate for IrDA is 115.2 kbps for which the clock frequency equals 1.843 MHz (this terminal is tied to the BAUDOUT of a UART).
GND 4 Ground
IR_RXD 6 I Infrared receiver data. IR_RXD is an IrDA-SIR-modulated input from an optoelectronics transceiver whose input pulses should be 3/16 of the baud rate period.
IR_TXD 7 O Infrared transmitter data. IR_TXD is an IrDA-SIR-modulated output to an optoelectronics transceiver.
RESET 5 I Active high reset. RESET initializes an IrDA-SIR-decode/encode state machine (this terminal is tied to a UART reset line).
U_RXD 3 O Receiver data. U_RXD is decoded (demodulated) data from IR_RXD according to the IrDA specification (this terminal is tied to SIN of a UART).
U_TXD 2 I Transmitter data. U_TXD is encoded (modulated) data and output data as IR_TXD (this terminal is tied to SOUT from a UART).
VCC 8 Supply voltage
