3.3.2.10. I²S
3.3.2.10.1. Description
The I²S interface is used to transfer serial digital audio to/from an external stereo DAC/ADC. This
interface is a 3 – wire interface:
- Serial clock
- Word select
- Serial data
I²S supports all the Tx/Rx slave/master modes:
- Transmitter – master
- Transmitter – slave
- Receiver – master
- Receiver – slave
Master or slave is determined by the device driving the serial clock and word select. The transmitter
sends data to the receiver.
Bidirectional I²S support is supported by configuring two of the five GSBI ports as I²S; one GSBI as
transmitter and the second GSBI as receiver. Two options are possible:
- Option 1: MDM as master (transmitter or receiver) and slave (transmitter or receiver); external
device as slave. The MDM transmitter and receiver cannot both be the master at the same time as
there will be data contention.
- Option 2: Both MDM transmitter and receiver are slave; external device as master.
At the standard configuration the NAD6200 module is master and the Codec slave. For other
configuration please contact Peiker acustics GmbH & Co.KG.
