TFDS3000
Integrated Infrared Transceiver Module IrDA (SIR)
Description
The TFDS3000 is an infrared transceiver for data commu-
nication systems. The transceiver is compatible to the
IrDA standard which allows data rates up to 115 kB/s.
An internal AGC (Automatic
Gain Control)
ensures
proper operation under EMI conditions.
