There's a very simple IrDA transceiver project in the Dec 2001 Silicon
Chip magazine (www.siliconchip.com.au) using a pair of TFDS4500
transceiver modules (made by Vishay Telefunken)

It's quite easy to use a diode and LP311 comparator or IS1U60 IR
receiver if you want to go the discrete way, many many components
that could be used, but the above is a lot simpler. 4-page article for
that particular project, but I daresay a datasheet for the TFDS4500
is lurking on the web that would give you all the info you need. HP,
Honeywell, Sharp, Optek, they're all at it. From SIR (serial, 115.2k) to
VFIR (very fast IR, 16M) You're pretty much spoilt for choice
