Circuit Protection of LCD and Camera Module
Solutions
Design Notes:
- Protection Application:
- For applications in which there are separate boards connected by flex circuits , there may be an issue with emitted and/or ingressed EMI and RFI. The flex circuit is unshielded, so can act like an antenna for high frequency signals.
- Solution Description:
- Multi-channel silicon protection arrays can be used to function as ESD protectors as well as EMI/RFI abatement controls. These products integrate ESD diodes, capacitors and resistors to provide a single device to replace up to 20 discrete components.
- Regulatory Issues:
- The IEC 61000-4-2 will be the most appropriate standard that applies for this port. It supplies a test method for verifying that the end product is not susceptible to ESD events.
