nowy Interface USB I2S kupiłem dwa potrzebuje kasy na projekty więc sprzedaje

w zestawie płytka i goldpiny wystarczy podpiąć zasilanie 3,3v i i2s z DAC sterowniki wysyłam na mail

jeden z najbardziej znanych implementacji układu od xmosa stabilny bardo dobrej jakości komponenty

atrakcyjna cena, więcej informacji:

XMOS DSD DXD 384kHz high-quality USB to I2S/DSD PCB (includes 2.54mm spacing 10x2row 30u gold plated header pins)

This is the best USB to I2S/DSD PCB for audiophile Diyer to enjoy.

Feature:

1) Newest XMOS chip and uses 48MHz oscillator to asynchronous reclock usb audio data to I2S line, old XMOS uses only 13Mhz oscillator, over 4x better jitter rejection theoretically.

2) Solid ground plane (a must for high speed digital circuit)

3) No Via in active circuit (via inductance always create jitter problem)

4) NDK NZ2520SD Ultra low phase noise oscillator and Murata capacitor sourced from Japan directly (guarantee no fake product from China)
According to the official datasheet, the phase noise of NZ2520SD is much better than the famous crystek 957 under 25khz(human listenable range)
For easier comparsion(lower is better), we overlay the two phase noise graph at the same scale, under 25khz(human listenable range) nz2520sd(red line) is better, over 25khz(human unlistenable range) crystek 957 is better.

5) Gold plated USB connector (Molex, FCI, or other depends on stock)

6) Compact size 50mm x 30mm

7) PCB uses external 3.3V(>150mA) regulated power supply, it is usually connected to the same 3.3v digital power DAC is using(warning: over-voltage or reverse-voltage can damage the xmos chip immediately, double check before power on)

8) Extreme diyer can cut and install series resistor in the pre-allocated 0805 footprint space in the I2S line to match their DAC line impedance
