DESCRIPTION
2
This multi-channel DAC is eminently suitable for DVD-like
applications in which 5.1 channel encoded signals are
used.
3
The UDA1328 is a single-chip 6-channel DAC employing
bitstream conversion techniques, which can be used either
in L3 microcontroller mode or in static pin mode.
The UDA1328 supports the I
lengths of up to 24 bits, the MSB-justified data format with
word lengths of up to 24 bits and the LSB-justified serial
data format with word lengths of 16, 18, 20 and 24 bits.
All digital sound processing features can be controlled with
the L3 interface e.g. volume control, selecting digital
silence type, output polarity control and mute. Also system
features such as power control, digital silence detection
mode and output polarity control.
Under static pin control, via static pins, the system clock
can be set to either 256f
de-emphasis can be set, there is digital mute and the
digital input formats can also be set.
