Silex technology SX-560 Regulatory Approval Requirements, General Purpose I/O Interface, Gpio

Regulatory Approval Requirements

The SX-560 has FCC and IC Modular Approval. This allows you to use the SX-560 in your device without any further agency testing for intentional radiation compliance (FCC Part 15 Subpart C and IC RSS-210). This Limited Modular Approval has the following requirements:

1.You must put the SX-560 FCC or IC number in a visible location on your product. These numbers are as follows:

a.FCC: N6C-SXSDWAG

b.IC: 4908B-SXSDWAG

2.You must use either a Silex-supplied SX-560 antenna (part number 108-00016-050) or a pole antenna similar to the one shown in Appendix C. If you use a non-Silex antenna, it must have a gain that is less than or equal to 2.1dBi @5.825GHz or 1.5dBi @2.4GHz. If you do not use a pole antenna, the Limited Modular Approval no longer applies and you must recertify your product for compliance with intentional radiation regulatory requirements.

3.You must use a special antenna cable that has ferrite beads built-in. This cable is available as an option from Silex (part number 131-00033-050). Alternatively, you can use a cable that meets the specifications shown in Appendix C.

4.In order to meet unintentional radiation standards (for example, FCC Part 15 Subpart B), Silex recommends a metal bracket similar to the one described in the previous section. This bracket provides additional grounding for the antenna connectors to reduce EMI.

5.There must be at least 20cm between the SX-560 antenna and the human body to avoid the possibility of exceeding the FCC radio frequency exposure limits. If your device requires smaller distances, then you must test your device as a system with the SX-560 for compliance with specific absorption rate (SAR) requirements.

IMPORTANT: Modular Approval only covers intentional radiation requirements. Although the SX-560 is designed to comply with FCC Part 15 Subpart B Class B unintentional radiation requirements, it is your responsibility to ensure that your device complies with unintentional radiation requirements when the SX-560 is installed.

General Purpose I/O Interface

Table 16 details the GPIO interface.
