CS4399
130-dB, 32-Bit High-Performance DAC
System Features
• Direct Stream Digital (DSD^®) path
• Enhanced  oversampling DAC architecture
— Patented DSD processor
— 32-bit resolution
— Up to 384-kHz sampling rate
— Low clock jitter sensitivity
— Auto mute detection
• Integrated high performance outputs
— 130-dB dynamic range (A-weighted)
– On-chip 50-kHz filter to meet Scarlet Book Super
Audio Compact Disk (SACD) recommendations
– Matched PCM and DSD analog output levels
– Nondecimating volume control with 0.5-dB step size
and soft ramp
– DSD and Pulse-code modulation (PCM) mixing for
alerts
— –108-dB total harmonic distortion + noise (THD+N)
— Dedicated DSD and DoP pin interface
— 110-dB interchannel isolation
• Serial audio input path
• Headphone detection
— Five selectable digital filter responses
— Headphone plug-in detection
– Low-latency mode minimizes pre-echo
— Popguard^® technology eliminates pop noise
– 110 dB of stopband attenuation
• Integrated PLL
— Supports sample rates from 32 to 384 kHz
— Support for 11.2896-/22.5792-, 12.288-/24.576-, 9.6-/ — I²S, right-justified, left-justified, TDM, and
19.2-, 12-/24-, and 13-/26-MHz system MCLK rates
DSD-over-PCM (DoP) interface
— Reference clock sourced from XTI/MCLK pin
— Master or slave operation
— System clock output
— Volume control with 0.5-dB step size and soft ramp
• Mono mode support
— 44.1 kHz deemphasis and inverting feature
• I²C control—up to 1 MHz
• 40-pin QFN or 42-ball CSP package option
Applications
• Smart phones, tablets, portable media players, laptops,
digital headphones, powered speakers, AVR, home
theater systems, Blu-ray/DVD/SACD players and pro
