An electronic system including a connector for an external device such as an infrared receiver includes a signal processor, responsive to the infrared receiver and an electrical isolation device such as an optocoupler, coupled between the connector and the signal processor. Such a system can further include electromagnetic interference suppression circuitry such as a ferrite bead, capacitors coupled to the earth potential, coupled between the connector and the optocoupler. Such a system can also further include electrostatic discharge suppression circuitry resistors coupled between the connector and the optocoupler.

Electrical isolation between IR receiver and further electronic circuits

An IR repeater is disclosed which is resistant to CFL interference. The IR repeater includes a receiver section for receiving an IR light signal representing a coded signal modulated by a modulating signal, and for detecting the coded signal. An oscillator generates a transmitter modulating signal, and a transmitter section, coupled to the receiver section and the oscillator, generates an IR light signal representing the detected coded signal modulated by the transmitter modulating signal.
