DESCRIPTION

GENERAL DESCRIPTION
The UDA1324TS is a single-chip stereo DAC employing
bitstream conversion techniques. The ultra low-voltage
requirements make the device eminently suitable for use
in portable digital audio equipment which incorporates
playback functions.
The UDA1324TS supports the I
word lengths of up to 20 bits, the MSB-justified data format
with word lengths of up to 20 bits and the LSB-justified
serial data format with word lengths of 16, 18 and 20 bits.
The UDA1324TS can be used in two modes: L3 mode or
static pin mode.
In the L3 mode, all digital sound processing features must
be controlled via the L3 interface, including the selection of
the system clock setting.
In the two static modes, the UDA1324TS can be operated
in the 256f
de-emphasis for 44.1 kHz and four digital input formats
(I
selected via static pins. The L3 interface cannot be used in
this application mode, so volume control is not available in
this mode.
