1 / 27 page SM5816AF SEIKO NPC CORPORATION —1 6-channel DSD-PCM Converter OVERVIEW The SM5816AF is a 6-channel DSD data to 6-channel 8fs or 2fs PCM data converter IC. During conversion, decimation filtering is performed using a filter with selectable fixed coefficients (4 sets) or optional filter coef- ficients that are written to the built-in RAM. Also, DSD input/outputs and PCM outputs are available for use in master/slave clock mode operation, in a wide range of system configurations, making it easy to construct a multi-channel DSD/PCM reproduction system. FEATURES I 512fs master clock (22.5792MHz, fs = 44.1kHz) I DSD inputs connected directly to outputs in through mode I Clock master/slave switching for DSD input/out- puts and PCM outputs I 2-system external data inputs (3-wire), with 2fs output data BCK and LRCK pins switchable between external inputs and internal filter outputs I Decimation filter characteristics • Fixed coefficients: 4 sets (8fs), 1 set (2fs) • Rewritable coefficients: 1 set (29 bit × 240 word) I Dither rounding function in 8fs/24-bit output mode, with switchable ON/OFF and summing position I PCM/DSD output independent muting operation I 8fs output format: [MSB-first left-justified 32-bit] or [MSB-first right-justified 24-bit] I 2fs output format: [MSB-first left-justified 32-bit] or [IIS 32-bit] I +6dB DSD gain switching function I System clock output switchable between external system clock and internal system clock I 3.3V ± 10% supply voltage I 5V tolerant inputs for direct connection to 5V logic outputs I −20 to 70°C operating temperature range I 80-pin QFP package APPLICATIONS I Multi-channel SA-CD players I SA-CD-compatible AV amplifiers ORDERING INFORMATION PINOUT (Top view) PACKAGE DIMENSIONS (Unit: mm) Device Package SM5816AF 80-pin QFP 21 VSS7 VDD2 22 DIR8CK 23 FMT8FS 24 FMT8WCK 25 F8BCK 26 F8WCK 27 F8SR 28 F8SL 29 F8SBR 30 VSS3 31 VDD3 32 F8SBL 33 F8SW 34 F8CT 35 F8FR 36 F8FL 37 SELDH2 38 SELDH1 39 DIR2CK 40 VSS4 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 INIT SYNC SELEXT SEL8FS XMTDSD XMTPCM SELFIR2 SELFIR1 SELRAM DIRDSCK2 DIRDSCK1 DSISR DSISL DSISW DSICT DSIFR DSIFL DSBCKF VDD6 0.18 0.05 0.1 0.125 0.025 0.05 0 to 10 12 ± 0.1 14 ± 0.4 0.5 0.5 ± 0.2 |
