Finally, I finish assembling my AD1865 PCB which converts standard I2S to AD1865 LSBJ format. This idea comes from pavouk, which provides the schematic then later I follow to design the PCB. Credit to him for this project.

So below is the appearance from the top side. The AD1865 main chip, followed by some 74HC converter, some DIY inductors and some ceramic bypass capacitors.

On the bottom side (this is 2-layers PCB), we can see another set of ceramic bypass capacitors and two I/V resistor. They are Shinkoh 2W version. Very huge size! Actually I need to put some filtering capacitors there. Thinking to grab my Black Gate NX Series or we can just go with Os-Con.

Appearance from the top. Quad towers of inductors to filter some unwanted noise (hope I’m doing right).

Appearance from the side. Well, those beautiful Shinkoh 2W Resistor is damned big.

Time to fire them up… ;) soon…

    Saya sabar menunggu hasilnya Mbah Jim :)

    Mudah2an hasilnya JOSS
    Kebetulan layout ngawur AD1865 ala saya sudah setengah jalan nih

    He he he… tinggal power on, Mbah…
    Takut jeblus, mana AD1865 ini cuman sebiji2nya…
    Mending pake batt 9V dulu ah dibantu 7805 ah…
    74HCT-nya juga moga2 enggak aspal… keterlaluan deh mau malsu ginian…
    Thanks.

    way to go pak Jim :) ..kita tunggu dendang nya
    setelah pakai batt monggo salas shunt reg nya di nyalaken he he..

    best, opa T

    Hello,
    I’m interested in your AD1865 and I’d like to know if your PCB works properly, also at 192Khz 24 bit.
    If yes do you have a PCb left?
    I’d like to buy if possible.
    Ciao

    Hi Guglielmo,
    I think it should work at 44.1/16. Dont know for higher bit/sample rate.
    Thanks.
