Overview
TFDS3000 Integrated Infrared Transceiver Module IrDA (SIR) Description The TFDS3000 is an infrared transceiver for data communication 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.
