NIPPON PRECISION CIRCUITS INC.—1 Preliminary Product Bulletin 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 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)
- Writable coefficients: 1 set I Dither rounding function in 8fs/24-bit output mode only, with switchable ON/OFF and sum- ming position I Mute 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 inputs I 20 to 70 C operating temperature range I 80-pin QFP package
