NIPPON PRECISION CIRCUITS—12
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 in
fl
uence 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.
