ASAHI KASEI [AK4393] AK4393 Advanced Multi-Bit 96kHz 24-Bit DAC The AK4393 is a high performance stereo DAC for the 96kHz sampling mode of DAT, DVD including a 24bit digital filter. The AK4393 introduces the advanced multi-bit system for modulator. This new architecture achieves the wider dynamic range, while keeping much the same superior distortion characteristics as conventional Single-Bit way. In the AK4393, the analog outputs are filtered in the analog domain by switched-capacitor filter SCF with high tolerance to clock jitter. The analog outputs are full differential output, so the device is suitable for hi-end applications. The operating voltages support analog 5V and digital 3.3V, so it is easy to I/F with 3.3V logic IC. • 128x Oversampling • Sampling Rate up to 108kHz • 24Bit 8x Digital Filter Ripple ±0.005dB, Attenuation 75dB • High Tolerance to Clock Jitter • Low Distortion Differential Output • Digital de-emphasis for 32, 48 & 96kHz sampling • Soft Mute • THD+N -100dB • DR, S/N 120dB • I/F format : MSB justified, 16/20/24bit LSB justified, I2S • Master Clock Normal Speed 256fs, 384fs, 512fs or 768fs Double Speed 128fs, 192fs, 256fs or 384fs • Power Supply to 5.25V Analog , 3 to 5.25V Digital • Small Package 28pin VSOP DIF0 DIF1 DIF2 DVDD DVSS DEM0 DEM1 AVDD AVSS LRCK BICK SDATA PDN SMUTE Audio Data Interface De-emphasis Control De-emphasis Soft Mute De-emphasis Soft Mute 8x Interpolator Modulator 8x Interpolator Modulator Control Register Clock Divider BVSS VCOM AOUTL+ AOUTLAOUTR+ AOUTR- CSN CCLK CDTI P/S MCLK CKS0 CKS1 CKS2 VREFH VREFL M0039-E-02 -1- 2003/09 ASAHI KASEI - Ordering Guide AK4393VF -40 ~ +85 °C 28pin VSOP 0.65mm pitch AKD4393 Evaluation Board - Pin Layout DVSS DVDD MCLK BICK SDATA View LRCK SMUTE/CSN DEM0/CCLK DEM1/CDTI DIF0 DIF1 DIF2 [AK4393] CKS2 CKS1 CKS0 P/S VCOM AOUTL+ AOUTLAOUTR+ AOUTRAVSS AVDD VREFH VREFL BVSS M0039-E-02 -2- 2003/09 ASAHI KASEI [AK4393] PIN/FUNCTION No. Pin Name 1 DVSS 2 DVDD 3 MCLK PDN 4 5 BICK SDATA 6 7 LRCK SMUTE CSN DFS 9 DEM0 10 CCLK DEM1 11 CDTI 12 DIF0 13 DIF1 14 DIF2 15 BVSS 16 VREFL 17 VREFH 18 AVDD 19 AVSS 20 AOUTR21 AOUTR+ 22 AOUTL23 AOUTL+ 24 VCOM 25 P/S 26 CKS0 27 CKS1 28 CKS2 I/O Function - Digital Ground Pin - Digital Power Supply Pin, 3.3V or 5.0V I Master Clock Input Pin I Power-Down Mode Pin When at “L”, the AK4393 is in power-down mode and is held in reset.
