CS4399
General Description
The CS4399 is a high-performance, 32-bit resolution, stereo audio DAC that supports up to 384-kHz sampling frequency.
The advanced 32-bit oversampled multibit modulator with mismatch shaping technology eliminates distortion due to
on-chip component mismatch. Proprietary digital-interpolation filters support five selectable filter responses with
pseudo-linear phase and ultralow latency to minimize pre-echos and ringing artifacts. Other features include volume
control with 0.5-dB steps and digital deemphasis for 44.1-kHz sample rate.
The patented on-chip DSD processor preserves audio integrity by allowing signal processing such as volume control and
50-kHz Scarlet Book recommended filtering to be applied directly to the DSD stream without an intermediate decimation
stage. Additional features like volume matching and channel mixing enable seamless transition between DSD and PCM
playback paths.
The CS4399 accepts I
2
S, right-justified, left-justified, and TDM-format PCM data at sample rates from 32 to 384 kHz. The
industry-standard high-speed I
2
C interface capable of up to 1-MHz operation provides easy configuration control. An
integrated PLL allows for maximum clocking flexibility in any system. Popguard

technology eliminates output transients
upon power-up or power-down events.
The CS4399 is available in a commercial-grade 42-ball WLCSP or 40-pin QFN package for operation from –10°C to
+70°C.
