If WaveI/O use isolated I2S outputs and remember to supply externally the isolator not sharing WaveI/O psu, you can use Audionote psu.

Default 8x

Hey Ian,

I successfully tested the I2S-PCM board at 8x speed: 352.8Khz & 384Khz with my AD1865 NOS DAC.

I finally finished soldering and adding the isolator adapter and it worked from the first power up.
Also changed my clocks on the dual clock board to a Crystek CCHD-957 for 45.xx Mhz and a Fox Xpresso for the 49.xx Mhz (as 99% of my FLACs are at 44.1Khz or multiple sample rate); I bought a 45.xx Mhz Fox too... will see how it behaves. It's a pity my other Crystek at 22.5792Mhz ended up in the drawer.

The source I'm using is an Amanero Combo384.

For this proof-of-work I simply upsampled by 2x, 4x, 8x manually some files with SoX and played them with Foobar2000 (+ASIO4ALL) into my test audio gear.
No listening tests yet on my main setup as I'm still sorting out how to stream my music: probably Squeezebox LMS with SoX to upsample by 8x and Squeezelite as client on either my SB Touch or something else....

Will come back with pictures and fairy tales when it is fully integrated

Thanks,
Zsolt

Hi Zsolt,

Glad to know your good news.

We already confirmed the I2S-PCM board works perfect for AD1865 and TDA1541. Now, Iím trying to test it on PCM1704 by myself. Just hope everything is OK.

Thanks Zsolt for your effort to the project, Iím looking forward to your pictures and your next progress.

Cheers,

Ian

Hi Ian:

Sorry, if this question has been answered earlier but is it a fully assembled board or one has to do some SMD soldering (which I have never done)?

Thanks!

The I2S to PCM converting daughter board would be a fully assembled and tested board together with some finished cables.

Don't worry about the SMT soldering.

Default PCM1704 Confirmed works perfectly with the PCM daughter board from 44.1 to 192 KHz

I donít have a PCM1704 DCA to test the PCM daughter board. A friend of mine sent his own BB PCM 1704 fixture to me. Thank you so much. It seems working perfect.

PCM1704 DAC connections:
LLLR to WCLK
CLK to BCLK
DL to DATAL
DR to DATAR

I2S to PCM daughter board configurations:
J24BIT short (24bit format),
JTAIL either short or open
All of other jumpers keep open

Test conditions:
Fs: 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz, 192KHz,
MCLK: 22.579, 24.576, 45.158, 49.152 MHz,
Without and with FIFO.
(The daughter board tested working bit perfect up to 384 KHz, but I donít have a 384 KHz music source to confirm.)

It works very well on all conditions. 192 KHz sounds much better than 44.1 KHz, over all, the daughter board sounds better than the original front end (DIR and digital filter at left half of the BB fixture), impressive. PCM1704 normally works with DF1704 digital filter running at 8x Fs, so, to play 44.1/48 KHz music, software based up-sampling plug-in is highly suggested, otherwise, you need to have very good NOS LPFs.

Some comment:
1, Continuous clock mode (JCONT) is also functional, but is not recommended. Stop clock mode theoretically comes with less noise.
2, JTAIL was specially designed for PCM1704/02. But the actual testing result shows PCM1704 works perfect either with JTAIL short or with it open. So now, JTAIL becomes an optional function, can be decided according to personal preference.
3, To get better signal quality, u.fl coaxial cables are highly recommended for the connections between DAC and the daughter board.
4, PCM1704 was powered at +-5V, the datasheet says the min Vih is 2V. I donít think there is any problem tolerance with PCM daughter board outputs which are 3.3V LVTTL logic level. Actual test also approved it.
5, If using a FIFO KIT in system, I am highly suggested place a isolator board between FIFO and clock board.

Now, we already confirmed the daughter board working perfect with AD1865, PCM1704 and TDA1541. Please let me know if you think itís OK to release.

I already ordered the final version (V2.0) prototype PCB. I will test it very soon. GB board will be based on this version.

Ian
