I shall publish my WM8804 design (tailored to fit my ES9022 module) in about a month's time.

Hi Fran,

I've no-more pcb's left, as the other four I made went to some other audio friends. I'd be happy enough (now that they are proven to work!) to do a run of them if there is enough interest.

Cheers,

Will

To ease the hunger of the waiting crowd, here are some latest pictures.

Shown here 2 standard modules with 50MHz low jitter XOs, separate LT1761 regulators, Murata MLCC capacitors, Susumu thin film SMD resistors, ultra-low ESR conductive polymer eletrolytics, and WIMA FKP2 output filtering caps .......

Default ES9022 in Synchronuous Mode

An advanced version of the ES9022 module using a 45.1584MHz XO and 2 ultra-fast single-gate Flip-Flops on a daughter board for dividing down to 11.2896MHz (to replace the TCXO in the QA550).

lovely neat work as usual Patrick, I would be interested in one of these perhaps to run the sub channel for my 3 ways. nice and neat and small, so could be easily built into the amp. that or ackos AKD24 using the same chip. which isnt quite as small though

am I right in assuming these are designed to slot into the SD reader? so with external battery pack you could have full blown portable solution with headphone amp given something to buffer/drive the output?

Default ES9022 Balanced

Yet another advanced version using a second level PCB with the 2nd ES9022 fed with inverted data from a single gate 741G04 (with its own LT1761 PSU).

The WIMA FKPs are soldered directly on the pins of the XLR connector.
