PRINCIPLES OF OPERATION
IrDA overview
The Infrared Data Association (IrDA) defines several protocols for sending and receiving serial infrared data,
including rates of 115.2 kbps, 0.576 Mbps, 1.152 Mbps, and 4 Mbps. The low rate of 115.2 kbps was specified
first and the others must maintain downward compatibility with it. At the 115.2 kbps rate, the protocol
implemented in the hardware is fairly simple. It primarily defines a serial infrared data wordto be surrounded
by a start bit equal to 0 and a stop bit equal to 1. Individual bits are encoded or decoded the same whether they
are start, data, or stop bits. The TIR1000 and TIR1000I evaluate only single bits and only follow the 115.2 kbps
protocol. The 115.2 kbps rate is a maximum rate. When both ends of the transfer are set up to a lower but
matching speed, the protocol (with the TIR1000 and TIR1000I) still works. The clock used to code or sample
the data is 16 times the baud rate, or 1.843 Mhz maximum. To code a 1, no pulse is sent or received for 1-bit
time period, or 16 clock cycles. To code a 0, one pulse is sent or received within a 1-bit time period, or 16 clock
cycles. The pulse must be at least 1.6
μ
s wide and 3 clock cycles long at 1.843 Mhz. At lower baud rates the
pulse can be 1.6
μ
s wide or as long as 3 clock cycles. The transmitter output, IR_TXD, is intended to drive a
LED circuit to generate an infrared pulse. The LED circuits work on positive pulses. A terminal circuit is expected
to create the receiver input, IR_RXD. Most, but not all, PIN circuits have inversion and generate negative pulses
from the detected infrared light. Their output is normally high. The TIR1000 and TIR1000I can decode either
negative or positive pulses on IR_RXD.
