I have designed a dac based on sabre9018aq2m with two SPDIF input and one usb input switchable through software. All features of SABRE9018aq2m are user selectable including filter settings, volume control, etc. The usb streamer is based on SA9227. The usb streamer supports the following playback format.


PCM 16/24/32 BIT and sampling rate 32/44.1/48/88.2/96/176.4/192/352.8/384 khz supported


Supports five modes for playback DSD data over usb audio stream


DSD 64 FOR 88.2K 32-BIT

DSD128 FOR 176.4K 32-BIT

DSD 256 FOR 325.8K 32-BIT

DSD 64 FOR 176.4K 24-BIT (DoP)

DSD 128 FOR 352.8K 24-BIT (DoP)


The dac board requires only 9v and a +/-12v symmetrical supply. The psu is based on LT3042 for both dac and usb section. Opamp LME49720 is used for IV section and it can be changed. Clock used for dac CCHD575 and usb section fox xpresso FXO-HC73. The dac board can be interfaced with LCD display. The dac board measures 107 mm x 115 mm. I will be providing driver for the SA9227. The dacs will be shipped out beginning second week of June. The kit will include dac board, LCD display and controller. DAC kit cost is €200+€10 shipping. Those are interested pm.
