Abstract
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.
