Antminer ctrl board SDR transceiver hardware quick start guide v0.9

Pinout (ADC13-14 currently not in use, but reserved them and 2 more pins for 16bit ADC). Mind that on the photo ADC/DAC pins count from 1, on the actual DAC/ADC boards from 0, so on the DAC board 13 pin equals 14 pin on the antimner board:

Scheme:

I’m using 61.44 clock, it should be soldered to Y2 pad (red dot without caption on the photo), but do not forget to add resistor and capacitor like in scheme attached. I just soldered clock output to the R49 pad 🙂

Clock — just typical single ended 61.44MHz 3.3v generator:

I bought this one — https://aliexpress.ru/item/10000282673529.html?spm=a2g2w.orderdetail.0.0.78e44aa6Vjj8Xh&sku_id=12000035895248861

It’s not so good, I bought it only for tests and posted here as an example.

All modules connected to the same clock generator — better to use coax cable.

You may want to find something better.

To boot from SD card set boot selection jumpers like that (first page on the scheme):

J12 — console UART input/output.

Power connector — 12v input with connector like for PC videocards:

Top pins +12v, bottom — ground.

Board has +5v output, but you may want to use linear regulator, I soldered it to the fan pads:
