FEATURES
1.1
General
2.4 to 3.6 V power supply
5 V tolerant digital inputs (at 2.7 to 3.6 V power supply)
24-bit data path for Analog-to-Digital Converter (ADC)
and Digital-to-Analog Converter (DAC)
Selectable control via L3-bus microcontroller interface
or I2C-bus interface; choice of 2 device addresses in
L3-bus and I2C-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
does not 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, the
clocks to these blocks are also 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 Amplifier (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 I2C-bus interface
Digital silence detection in the interpolator (playback)
with read-out status via L3-bus or I2C-bus interface
Easy application.
1.2
Multiple format data input interface
Slave BCK and WS signals
I2S-bus format
MSB-justified format compatible
LSB-justified format compatible.
1.3
Multiple format data output interface
Select option for digital output interface: either the
decimator output (ADC signal) or the output signal of the
digital mixer which is in the interpolator DSP
Selectable master or slave BCK and WS signals for
digital ADC output
Remark: SYSCLK must be applied in WSPLL mode and
master mode
I2S-bus format
MSB-justified format compatible
LSB-justified format compatible.
1.4
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
Digital left and right independent volume control and
mute from +24 to
63.5 dB in steps of 0.5 dB.
