Cirrus Logic reserves the right to modify this product without notice. 1 Copyright © Cirrus Logic, Inc. 2002 (All Rights Reserved) http://www.cirrus.com CS4392 24-Bit, 192 kHz Stereo DAC with Volume Control Features Complete Stereo DAC System: Interpolation, D/A, Output Analog Filtering 114 dB Dynamic Range 100 dB THD+N Up to 192kHz Sample Rates Direct Stream Digital Mode Low Clock Jitter Sensitivity Single +5 V Power Supply Selectable Digital Filters – Fast and Slow roll-off Volume Control with Soft Ramp –1dB Step Size – Zero Crossing Click-Free Transitions Direct Interface with 5 V to 1.8 V Logic ATAPI mixing functions Pin compatible with the CS4391 Description The CS4392 is a complete stereo digital-to-analog sys- tem including digital interpolation, fifth-order delta-sigma digital-to-analog conversion, digital de-emphasis, vol- ume control, channel mixing and analog filtering. The advantages of this architecture include: ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and tempera- ture, and a high tolerance to clock jitter. The CS4392 accepts PCM data at sample rates from 4 kHz to 192 kHz, DSD audio data, has selectable digital filters, and consumes very little power. These features are ideal for DVD, SACD players, A/V receivers, CD and set-top box systems. The CS4392 is pin and register compatible with the CS4391, making easy performance upgrades possible.
