C-bus mode
Remark: This device does not have a static mode
Supports sample frequencies from 8 to 55 kHz for the
ADC part, and 8 to 100 kHz for the DAC part. The ADC
cannot support DVD audio (96 kHz audio), only
Mini-Disc (MD), Compact-Disc (CD) and Moving Picture
Experts Group Layer-3 Audio (MP3). For playback
8 to 100 kHz is specified. DVD playback is supported
Power management unit:
Separate power control for ADC, Automatic Volume
Control (AVC), DAC, Phase Locked Loop (PLL) and
headphone driver
Analog blocks like ADC and Programmable Gain
Amplifier (PGA) have a block to power-down the bias
circuits
When ADC and/or DAC are powered-down, also the
clocks to these blocks are stopped to save power
Remark: By default, when the IC is powered-up, the
complete chip will be in the Power-down mode.
ADC part and DAC part can run at different frequencies,
either system clock or Word Select PLL (WSPLL)
ADC and PGA plus integrated high-pass filter to cancel
DC offset
The decimation filter is equipped with a digital Automatic
Gain Control (AGC)
Mono microphone input with Low Noise Amplifier (LNA)
of 29 dB fixed gain and Variable Gain Control (VGA)
from 0 to 30 dB in steps of 2 dB
Integrated digital filter plus DAC
Separate single-ended line output and one stereo
headphone output, capable of driving a 16
load. The
headphone driver has a built-in short-circuit protection
with status bits which can be read out from the
L3-bus or I

ADC front-end features
ADC plus decimator can run at either WSPLL,
regenerating the clock from WSI signal, or on SYSCLK
Stereo line input with PGA: gain range from 0 to 24 dB
in steps of 3 dB
LNA with 29 dB fixed gain for mono microphone input,
including VGA with gain from 0 to 30 dB in steps of 2 dB

GENERAL DESCRIPTION
The UDA1380 is a stereo audio coder-decoder, available
in TSSOP32 (UDA1380TT) and HVQFN32 (UDA1380HN)
packages. All functions and features are identical for both
package versions. The term `UDA1380' in this document
refers to both UDA1380TT and UDA1380HN, unless
particularly specified.
The front-end of the UDA1380 is equipped with a stereo
line input, which has a PGA control, and a mono
microphone input with an LNA and a VGA. The digital
decimation filter is equipped with an AGC which can be
used in case of voice-recording.
The DAC part is equipped with a stereo line output and a
headphone driver output. The headphone driver is capable
of driving a 16
load. The headphone driver is also
capable of driving a headphone without the need for
external DC decoupling capacitors, since the headphone
can be connected to a pin V
REF(HP)
on the chip.
In addition, there is a built-in short-circuit protection for the
headphone driver output which, in case of short-circuit,
limits the current through the operational amplifiers and
signals the event via its L3-bus or I
2
C-bus register.
The UDA1380 also supports an application mode in which
the coder-decoder itself is not running, but an analog
signal, for instance coming from an FM tuner, can be
controlled in gain, and applied to the output via the
headphone driver and line outputs.
The UDA1380 supports the I
2
S-bus data format with word
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 or 24 bits
(LSB-justified 24 bits is only supported for the output
interface).
The UDA1380 has sound processing features in playback
mode, de-emphasis, volume, mute, bass boost and treble
which can be controlled by the L3-bus or I
2
C-bus interface.
