General description
The UDA1384 is a single-chip consisting of 4 plus 1 Analog-to-Digital Converters (ADC)
and 6 Digital-to-Analog Converters (DAC) with signal processing features employing
bitstream conversion techniques. The multichannel configuration makes the device
eminently suitable for use in digital audio equipment which incorporates surround feature.
The UDA1384 supports conventional 2 channels per line data transfer conformable to the
I
2
S-bus format with word lengths of up to 24 bits, the MSB-justified format with word
lengths of up to 24 bits and the LSB-justified format with word lengths of 16 bits, 20 bits
and 24 bits, as well as 4 channels to 6 channels per line transfer mode. The device also
supports a combination of the MSB-justified output format and the LSB-justified input
format. The UDA1384 has special sound processing features in the Direct Stream Digital
(DSD) playback mode, de-emphasis, volume and mute which can be controlled via the
L3-bus or I
2
C-bus interface.
