They volume-control engine that does not deliver premium analog performance and decimate the data stream, thereby sound quality by utilizing low-latency digital maintaining the native sampling rate of filtering, fifth-order, multi-bit, Delta-Sigma 2.8224 MHz and preserving the integrity of digital-to-analog conversion, logarithmic the SACD data format. Also included is an digital-volume control and switched- on-chip 50 kHz filter that complies with capacitor analog filtering. Both ICs use recommendations in the SACD standards. patented automatic mode selection based Cirrus Logic's techniques for providing on sample rate detection to support PCM SACD volume control and filtering offers data at sample rates from 4 kHz to 192 manufacturers the ability to add SACD at kHz, and a dedicated interface is included no additional cost in the analog section of for DSD audio data.
