Various options exist to implement the pulse encoding and decoding that is required for the
Infrared Data Association serial infrared physical layer. The most commonly used option is
the use of a dedicated integrated circuit such as those available from Texas Instruments,
Agilent or Vishay. Also occasionaly microcontrollers are available with IrDA enabled ports.
Another solution is to use an implemention with programmable logic. Especially when a PLD, FPGA
or other programmable logic device is already in use in a project, this can be a very cost
This implementation uses the programmable logic way. As a component it can be instantiated in
VHDL the same way as it's silicon equivalents on a printed circuit board.
White Bream can offer additional services to merge other logic functionality in a design
together with this encoder/decoder to create a complete 'one chip' solution. You may

requirements and the possibilities.
