ΣDECO SM588× series
Audio 3rd-order Σ∆ D/A Converter
NIPPON PRECISION CIRCUITS INC.
OVERVIEW
The ΣDECO SM588× series, fabricated using NPC’s Molybdenum-gate CMOS process, are D/A converter ICs
for digital audio, that provide all the basic converter functions in miniature 8-pin packages. They each feature
built-in 8-times oversampling digital filter, Σ∆ jitter-compensated D/A converter, and post-analog lowpass fil-
ter converter stages required for digital audio. They can sample at up to 96kHz for 16 or 24-bit input word
length. A type with built-in deemphasis filter is also available for applications requiring deemphasis.

FUNCTIONAL DESCRIPTION
System Clock (CLK)
The system clock CLK frequency varies with device within the series as shown below, where fs is the input
frequency on LRCI.
Note that the input clock accuracy and signal-to-noise ratio greatly influence the AC analog characteristics.
The D/A converter operates at the speed shown in the following table.

System Reset
The SM588× series devices incorporate a built-in power-ON reset circuit for system reset.
When power is applied, the internal arithmetic operation and output timing counter are reset, and then reset
again and timing synchronized to the external input on the next LRCI rising edge. After system reset, the out-
puts are muted until the 9th rising of LRCI when output muting is released.
When the timing is reset, the PWM outputs may generate an output noise. An external muting circuit may be
required to prevent this output noise.

1. The 2-wire type supports bit clocks of 48fs (384fs) or 64fs (256fs/512fs) only.
2. The 3-wire type supports bit clocks of up to 64fs.
Input timing
3-wire input (DATA, LRCI, BCKI)
Serial data bits on DATA are read into the SIPO register (serial-to-parallel converter register) on the rising
edge of the bit clock BCKI, and then converted to parallel data.
The arithmetic operation and output timing are independent of the input timing. Accordingly, after a reset, as
long as the clock frequency ratio between LRCI and the system clock CLK is maintained, phase differences
between LRCI, BCKI and the system clock CLK do not affect the functional operation. Also, any jitter present
on the data input clock does not appear as output pulse jitter.
2-wire input (DATA, LRCI)
Serial data bits on DATA are read into the SIPO register (serial-to-parallel converter register) on the rising
edge of an internally generated bit clock, and then converted to parallel data.
Deemphasis Filter (DEEM: 2-wire input)
The 2-wire type with built-in digital deemphasis filter is designed to operate at 44.1 kHz. Deemphasis is ON
when DEEM is HIGH, and OFF when DEEM is LOW.
