¿É¼ÇÁ¤º¸[(193)No SAA7220]
Name: CDM4-310 coaxial output board Size: 100mm * 65mm (excluding the protruding part) Power supply: AC9V (can be changed to AC dual 9V, suitable for 310 board common transformer)
Description
1,This output board is mainly installed SAA7220 as S/PDIF output and DF output. 2, while compatible with PCF2705 and PCF3523 as IIS to coaxial output, but does not have DF function. Can also be used through the adapter board CS8404/CS8405/WM8805, etc. 3, it is highly recommended to use a small independent transformer to supply AC9V. Transformer, shared when the upper left corner of the two diodes cut off, power supply input seat Connect the 3-wire double 9V ends, the middle 0V connected to the negative terminal of the filter capacitor.
Note:
After modification, the voltage at both ends of the filter capacitor should be DC10V-12V without loading the chip first.
Shipping Instructions
Goods do not include SAA7220 chip, the motherboard comes with a 6P connection cable, a 2P Connection cable. About 20CM.
Modification instructions:
remove the original crystal and the two capacitors connected to a resistor. Connect MCK to pin 26 of 7310, clock GND to GND near the original crystal, then connect WS to pin 4 of 7310 (TDA1543 pin 2), CL to pin 3 of 7310 (TDA1543 pin 1), DA to pin 2 of 7310 (TDA1543 pin 3). CL connects to pin 3 of 7310 (TDA1543 pin 1), DA connects to pin 2 of 7310 (TDA1543 pin 3), EF connects to pin 1 of 7310, and MU connects to pin 18 of 7310. MU connected to 7310 pin 18 (ZC99696 pin 17), and then connected to the IIS input block GND to the 7310 near the GND. Test normal and fix with hot melt adhesive
