Abstract:
A system having an infrared receiver is shown, where the system includes an infrared receiver circuit configured to receive an infrared data signal using a receive photodiode and compensate for an ambient light level incident on the receive photodiode by generating a DC ambient current signal, where the DC ambient current signal is accessible external to the infrared receiver circuit. The system also includes a control circuit configured to receive the DC ambient current signal and, responsive thereto, determine the ambient light level and generate a display illumination control signal accordingly.
