4500 General Description
The TFDS4500 and TFDT4500 are infrared transceivers for data communication systems. The transceivers are compliant to the IrDA standard and allow data rates up to 115 kbit/s. An internal AGC (Automatic Gain Control) ensures proper operation under adverse EMI conditions.
The internal IRED driver can be connected by an external current control resistor to an independent unregulated power supply, VCC2. This adds circuit design flexibility and efficient serial drive capability for external IREDs for high power applications.
