5 OEMOperatingInstructions
The master module provides four I2S inputs to support 2.0 to 7.1 audio channel configurations. It
accepts up to eight channels of 24-bit uncompressed digital audio at sample rates up to 48 KHz.
The master module is controlled through a simple API via I2C.
Operating instructions at the electrical I/O and software interface level are not relevant to the end
user and are proprietary in nature. The end user should not have understanding of how to manipulate
the transmitter at this level.
6 Compliancewithcountrycoderequirements
This device is in compliance with the software configuration control and county code requirements
of KDB 594280.
Below are the guidelines that the ODMs will follow to comply with the software configuration
control and county code requirements of KDB 594280.
• ODMs will request Summit Semiconductor to provide them with a software program for
a particular country that will allow them the access over the audio configuration fields.
• Summit will provide the software program with the country code already hard coded to a
particular country that the ODM has requested so that ODMs can change only audio
related configuration.
• Once the ODM completes the audio configuration changes and runs the software
program, the country code is set automatically without ODM input. The program then
verifies the settings for the ODM guarantying the correct application of the country code.
ODMs are required to sign an attestation statement ensuring that a module programmed to a specific
country code will only be used in products shipped to that country.
