Audio Multi-function Digital Filter
OVERVIEW
The SM5841H is an 8-times oversampling (interpo-
lation) digital filter for digital audio reproduction
equipment. It accepts 16 or 18-bit input data, and
outputs data in 16, 18 or 20-bit format, making a
wide range of interfaces possible. It also features
digital deemphasis for 3 sampling frequencies, a
noise shaper to reduce quantization noise, a DC off-
set output and other circuits.
