Smile My new AD1851 DAC

It's my new DAC builded on AD1851N-J DAC and DF1700 digital filter. This DAC has 4 SPDIF inputs and 1 I2S (TTL) input with 16.344MHz or 11.2896 MCLK output for CD transport synchronisation. The DAC uses ultra low jitter oscillator (typical jitter about 5-7 ps RMS) and reclock unit, which may work in 3 modes: SYNCHRONOUS, when used synchronous interface as I2S or synchronous SPDIF, ASYNCHRONOUS, when used SPDIF, or BYPASS.

Supported chips:

DAC: AD1851,AD1861,AD766,AD1856,PCM56,PCM61.

DF: PMD100, SM5813, DF1700, DF1704, DF1706(with 3.3V supply), SM5842 (only in 18 bit output mode )
