Soulnote D-2 D/A Converter

A DDS using the LMX2594 super low jitter features with external clock generator inputs.A perfectly symmetric, discrete non-NFB D/A converter that uses a total of four ES9038PRO circuits and supports non-over sampling. The DSS uses the LMX2594 from Texas Instruments D/A converter formats that recreate the required master clock from standard clocks typically use a DDS (Direct Digital Synthesizer). The performance of external clock generators in this format guarantees extreme frequency accuracy (e.g. how many seconds of deviance will occur over tens of thousands of years), but jitter (fluctuations in waveform width arising in the clock) and the resulting phase noise are highly dependent on the performance of the DDS. By convention, audio equipment generally uses DDS-specific ICs with 10 ps (picosecond) jitter functions, but the D-2 is the first device to use Texas Instrument's PLLatinum™ RF LMX2594 synthesizer for an audio DDS. The LMX2594 synthesizer was developed for radars and measurem
