Connectors
Module is equipped with Con1 and Con3 connectors. They make possible to connect module to the digital system with I2S interface. Con2 connector (Jack stereo 3.5mm) is used to connect a headphones, loudspeaker or audio amplifier (output voltage 2.2V RMS@10 kΩ).
Configuration
STB jumper is used to switch a converter into Standby mode. F1 i F2 jumpers are used for selection of data format, which are converted by converter.
| STB jumper position | Standby mode… |
|---|---|
| 0 | …off |
| 1 | …off |
| F1 jumper | F2 jumper | Data format |
|---|---|---|
| 0 | 0 | 16 bits/channel, processed 16 last transmitted bits (right justified), synchronization with rising edge of BCLK |
| 1 | 0 | 24 bits/channel, processed 24 last transmitted bits, read on rising edge of BCLK |
| 0 | 1 | 16..24 bits/channel, processed the latest transmitted bits (left justified), read on rising edge of BCLK |
| 1 | 1 | I2S, 16..24 bits/channel, read on rising edge of BCLK |
