TFDS3000

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. Features D D D D Compatible to IrDA standard SMD side view Low profile (height = 5.6 mm max.) Microcomputer compatible D D D D No external components Low power consumption Wide supply voltage range (3 to 5.5 V) AGC for EMI immunity Pin description: 1: IRED cathode 2: Rxd (output) 3: VCC (supply voltage) 4: Ground 5: NC *) 6: **) 7: Txd (input) 8: IRED anode Guide pins internally connected to ground *) **) Vcc 3 Driver 2 Amplifier Comparator 8 6 SD 7 Txd Control logic Driver 1 Rxd optional sensitivity control for OEMs only shut-down, not for new development 95 11227 4 GND Figure 1.
