02_IC Block Diagram.pdf8. IC Block Diagrams 8-1 Main 1. AK4355 AK4355 192kHz 24-Bit 6ch DAC for DVD-Audio GENERAL DESCRIPTION ESCRIPTION The AK4355 offers the perfect mix for cost and performance based multi-channel audio systems. AKM's advanced multi-bit architecture delivers a wide dynamic range and low outband noise. The AK4355 has full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The 24 Bit word length and 192kHz sampling rate make this part sampling ideal for a wide range of application including DVD-Audio. FEATURES Sampling Rate: 8kHz to 192kHz 24Bit 8 times Digital Filter with Slow roll-off option THD+N: -90dB DR, S/N: 106dB High Tolerance to Clock Jitter Low Distortion Differential Output Digital De-emphasis for 32, 44.1 & 48kHz sampling Zero Detect Pin Channel Independent Digital Attenuator with soft-transition Soft Mute I/F format: 24-Bit MSB justified, 24/20/16-Bit LSB justified or I2S Master Clock Norma
