Convert the IIS signal to the coaxial SPDIF signal and output two clock signals at the same time. The digital isolation transformer (pad compatible with SC947-02LF) does not have to be soldered, and needs to be soldered by yourself.
The clock adopts the new imported TCOX+PLL, a total of 2 sets of clock output, CLKOUT1 (driving DIT4192), CLKOUT2; the output driver is driven by 2 DS8921s, and there are 3 sets of digital outputs: one set of optical fiber, one set of RCA, one set of XLR, including one With a 2PIN power cord, a 6PIN IIS line, and a clock line (one end with a connector and the other bare wire forked). SW1 sets the DIT4192 master clock magnification and I2S data format:
The clock output level is 3.3v, C26 is the SPDIF output-to-ground capacitor, which can be removed as required. The output frequency of CLKOUT1/CLKOUT2 can be set through SW2:
Some DSP wiring methods are as follows
1. CDPRO2 connection:
Plug the 6pin cable directly into the CDPRO I2S output port.
SW2: Up and down (384fs/192fs), SW1: Up and down (24bitSTD/384fs), CLKOUT1 outputs 16.9344Mhz, CLKOUT2 outputs 8.4672Mhz.
2. Philips/SAA7310 connection method (310 board uses this DSP):
SAA7310.Pin4---->Pin3 of the 6pin socket on the digital board (counted from left to right) WCLK
SAA7310.Pin3---->Pin2 of the 6pin socket on the digital board (counted from left to right) SCLK
SAA7310.Pin2---->Pin4 of the 6pin socket on the digital board (counting from left to right) DAT
SW2: up, up and up (256fs/256fs), SW1: up and down (24bitSTD/256fs)
(In light areas such as CM206, you need to pick up pin 18 of SAA7310 and connect it to pin 5, otherwise there will be noise when selecting songs), CLKOUT1 and CLKOUT2 output 11.2896Mhz, and pin 26 of SAA7310 is clock input and pin 25 is clock output.
3. SONY/CX23035 connection method
cx23035.Pin80---->Pin3 of the 6pin socket on the digital board (counted from left to right) WCLK
cx23035.Pin77---->Pin2 of the 6pin socket on the digital board (counted from left to right) SCLK
cx23035.Pin78---->Pin4 of the 6pin socket on the digital board (counting from left to right) DAT
SW2: Up and down (384fs/192fs), SW1: Up and down (16bitRJ/384fs), the clock CLKOUT2 is connected to CX23035.Pin53 and the jumper between CX23035.Pin53 and CX23034.Pin4 is disconnected. CLKOUT1 outputs 16.9344Mhz, and CLKOUT2 outputs 8.4672Mhz.
The crystal oscillator frequency of this type of machine is 67.7376Mhz, which is connected to CX20152.Pin26/Pin27(DA), CX20152.Pin3 outputs 16.9344Mhz divided by 4 and buffered by 74HC04, then connected to CX23034.Pin1, CX23034.Pin4 outputs 8.4672M directly Connect CX23035.Pin53, the above is to replace the CX23035 clock with the 8.4672Mhz clock.
