Mine shipped today . Have no idea if it is any good, but at that price it is worth a look I think.

This is the simplest DAC I have ever made
very good for use as a fast testing the i2s signal.
the DAC Digital GND and analog GND is connect direct under the DAC, plus star ground, and bottom layer is a prefect solid ground plane etc. the layout should be prefect, many people told it's an un-polish diamond, welcome to share the polish result the es9023 datasheet with official schematic is available for download.

Hi,

What value / type are there for the capacitors C14 (CN/CP) and C15 (NEG) and for AVCC ? I guess you use PPS film for 4700pF output filter ?

Thanks.

The value used is the same as the official datasheet
The integrated charge pump is designed to work and output a specific amount of current. If the (CN/CP) cap is too large, the charge pump can overload and seriously affect the performance. The output filter uses C0G cap, there are preallocted 5mm lead space for diyer to try the popular PPS film cap

Yes, I made another es9023 with 50mhz epson saw xo. Saw xo seems to make fundamental sound stronger and maybe less harmonics so the instrument separate more. But it can work with any 50mhz for sure. I see there are pads for this, but only one regulator - 3.6V ? - so xo will need 3.3V regulator also ?

I know ES9023 can work with 50MHz XO. What I mean is, anyone make this es9023 board on ebay work in Async with 50MHz XO with good result.

According to this pcb layout shown on #4, it may not working good with 50MHz XO.
