Description:
- The latest version adopts CS8412CS-SOP package. The functions are the same as the old version
- Data webpage (copy to browser and open): http://www.cdream5.com/htm/1540_DR.htm
-
This board is stripped from the 1541 1540DAC previously designed by the
webmaster. You can use this board to drive the TDA1540DAC directly.
This board can be used to modify some old CD players; some old CD
players such as CDM2 CDM4 and the like, bald head It is aging, but the
internal DAC is normal, you can use this board to drive the built-in
1540, so that the CD function can use the residual temperature.
- The
board has a high-precision PLL circuit and supports a digital output
chip with 256fs output. Most digital receiving chips and I2S signals can
support
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

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
