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.
Features
D Compatible to IrDA standard
D SMD side view
D Low profile (height = 5.6 mm max.)
D Microcomputer compatible
D No external components
D Low power consumption
D Wide supply voltage range (3 to 5.5 V)
D AGC for EMI immunity
