Method 1. Connect the two sets of power supply +5V, +12V GND -12V needed on this board, remove the SAA7030 chip on the original board, and connect the digital signal output directly to the corresponding pins of SAA7030
Method 2. Connect the two sets of power supply +5V, +12V GND -12V needed on this board, remove the SAA7030 chip on the original board, and connect the digital signal output directly to the corresponding pin of the 1540 chip
Method 3: Remove SAA7030 on this board, this board is only connected to +5V power supply, this board is set to OS (16bit) mode (J7, J8, J10, J11, J12 disconnected), keep SAA7030 on the original board, cut off the original SAA7030 input signal wires 17, 18, 19, 20, 21 and other chip connection wires, connect 17, 18, 19, 20, 21 of SAA7030 on the module board to 12, 17, 18 of SAA7030 on the modified board ,19,20,21; this modification can only support up to 48K
The board supports I2S 256fs 384fs input..
If your receiving board supports 384FS output (such as TDA1315H, dir9001), short-circuit JP1 2-3
If your receiving board does not support 384FS output, such as CS8412, etc., you can shorten JP 2-3
