ELECTRICAL ISOLATION BETWEEN IR RECEIVER AND FURTHER ELECTRONIC CIRCUITS. |
摘要 |
An electronic system including a connector (J1) for an external device such as an infrared receiver (12) includes a signal processor (20), responsive to the infrared receiver and an electrical isolation device such as an optocoupler (18), coupled between the connector (J1) and the signal processor (20). Such a system can further include electromagnetic interference suppression circuitry such as a ferrite bead (14), capacitors (C1, C2) coupled to the earth potential, coupled between the connector (J1) and the optocoupler (18). Such a system can also further include electrostatic discharge suppression circuitry resistors (R1, R2) coupled between the connector (J1) and the optocoupler (18). Application: infrared remote control devices.
