Sound Canvas SC-55

[Veda82]

Hi, I was wondering if this could be used also with a Sound Canvas SC-55.

In particularly, which input points shall be used for sysclk, data, qclk, wclk and reset?

Thanks in advance!

According to SC55 service manual, you should look at DAC IC7 - UPD6376, where13pin@IC7 - LRCK(WCLK), 15pin@IC7 - SDATA, 16pin@IC7 - BCLK.

SC-55 is described as 16bit 32kHz, for that bit clock should be (16x2x32000)=1.024MHz, and the master clock must be bclk x2 or bclk x4 or x8 or x16. Reset line can be found at IC21 pin 21 or IC31 pin 1.

Master clock needs to be found at the clk pins mentioned in service manual, without real device i can't say for sure which line is valid for that.

Ok, I will try using your informations.

Thanks for your work/project and support!

Don't forget that you must configure dif0-dif2 , fs0-fs3 according to 16bit right justified , 32kHz, and cks0-cks1 according to mclk/lrck divide.

Yes, already noticed, thank you!

Still waiting for the boards/components...

Once I try I'll report my findings.

Just for attention, in neighbor issue we found that the MCLK pin also can be feed with BCK line. It works.

Thanks! Unfortunately I'm still waiting for the chips... eBay supplier was a scam, let's hope I have more luck from AliExpress...
