Upgrade the weapon of CS8412, easily realize the upgrade of CS8412...The resolution and sound density are obviously higher than that of CS8412...
For the input interface circuit, please refer to the last picture of the display picture. Some decoder boards are different, please modify by yourself...(Note: AK4118 and WM8804 have the same interface circuit)
DIR9001 to CS8412:
*The main clock MCLK is 256fs or 384fs(Can be set by solder joints on the board)
*Support up to 96K sampling rate
*The output format can be set to the 2 most commonly used formats through pins:
1, 16bit, MSB-first, right-justified, suitable for DF1700, SM5813, etc...
2. I2S, suitable for TDA1541, saa7220, pcm1794, etc...

AK4118 to CS8412:(New PCB Immersion Gold Edition)The pictures of the old version are for reference only, and the shipment is subject to the new version.
*The main clock MCLK is 256fs
*Up to 192K sampling rate is supported
*The output format can be set to the 2 most commonly used formats through pins:
1, 16bit, MSB-first, right-justified, suitable for DF1700, SM5813, etc...
2. I2S, suitable for TDA1541, saa7220, pcm1794, etc...
pay attention:
1. The signal input of the small board is the 9th pin. When replacing part of the decoder board CS8412, pay attention to check the following input circuit matching.
2. If the 9th and 10th pins of some decoder boards CS8412 are directly connected to the digital transformer, the 9th pin of the old version of AK4118 needs to be connected in series with 0.01~0.1U DC blocking capacitors.

CS8416 to CS8412:
*The main clock MCLK is fixed at 256fs
*The output format is fixed to I2S
*Support 44.1k~192k sampling rate
Tips:
1. When receiving a 192k sampling rate signal, the output frequency of the 256fs master clock is as high as 49.152MHz, please pay attention to whether the device you are connecting supports…Friends who need to change 128fs, please note…
2. It can be easily upgraded to 192k/24bit with our NOS board instead of cs8412+sm5813/df1700.…

WM8804 to CS8412:
*The main clock MCLK is 256fs
*Support up to 192K sampling rate
*The output format can be set to I2S or 16bit, MSB-first, right-justified

Notice:
1. The 28th pin of this board is the error control pin.
2. It is only suitable for upgrading the CS8412 decoding in hardware mode and main mode.
3. The boards sent out are guaranteed to be tested and used normally.
The chip may be damaged due to the different technical level of each person or operation error. Therefore, the board sold does not accept any return or exchange. Friends who accept it will come to shoot again.
The freight is actually collected without bargaining.
