1 / 27 page ASAHI KASEI [AK4357] MS0088-E-02 2002/07 - 1 - GENERAL DESCRIPTION The AK4357 is six channels 24bit DAC corresponding to digital audio system. Using AKM's advanced multi bit architecture for its modulator the AK4357 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4357 has full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4357 accepts 192kHz PCM data and 1-Bit DSD data, ideal for a wide range of applications including DVD-Audio and SACD. FEATURES o Sampling Rate Ranging from 8kHz to 192kHz o 24Bit 8 times Digital Filter with Slow roll-off option o THD+N: -90dB o DR, S/N: 106dB o High Tolerance to Clock Jitter o Low Distortion Differential Output o DSD Data input available o Channel Independent Digital De-emphasis for 32, 44.1 & 48kHz sampling o Zero Detect function o Channel Independent Digital Attenuator with soft-transition (3 Speed mode) o Soft Mute o 3-wire Serial Interface for Volume Control o Master clock: 256fs, 384fs, 512fs or 768fs (PCM Normal Speed Mode) 128fs, 192fs, 256fs or 384fs (PCM Double Speed Mode) 128fs or 192fs (PCM Quad Speed Mode) 512fs or 768fs (DSD Mode) o Power Supply: 4.75 to 5.25V o 48pin LQFP Package SCF DAC DATT DZF LOUT1+ LOUT1- SCF DAC DATT ROUT1+ ROUT1- SCF DAC DATT LOUT2+ LOUT2- SCF DAC DATT ROUT2+ ROUT2- SCF DAC DATT LOUT3+ LOUT3- SCF DAC DATT ROUT3+ ROUT3- Audio I/F Control Register AK4357 MCLK LRCK BICK DCLK DSDL1 DSDR1 CSN CCLK CDTI SDTI1 SDTI2 SDTI3 DSDL2 DSDR2 DSDL3 DSDR3 PCM DSD 192kHz 24-Bit 6ch DAC with DSD Input AK4357 |
