Introduction
10
SLES112 — June 2004
TAS5028A
The DAP accepts 24-bit data signal from the serial data interface and outputs 32-bit data to the PWM section.
The DAP supports two configurations, one for 32
kHz to 96
kHz data and one for 176.4
kHz to 192
kHz data.
1.4.5.1
TAS5028A Audio Processing Configurations
The 32
kHz–96
kHz configuration supports eight channels of data processing that can be configured as eight
channels or six channels with two channels for separate stereo line outputs.
The 176.4
192 kHz configuration supports three channels of signal processing with five channels passed
though (or derived from the three processed channels).
To efficiently support the processing requirements of both multi-channel 32 – 96-kHz data and the two channel
176.4 and 192-kHz data, the TAS5028A supports separate audio processing features for 32 –96-kHz data
rates and for 176.4 and 192 kHz. See Table 2 for a summary of TAS5028A processing feature sets.
1.4.5.2
TAS5028A Audio Signal Processing Functions
The DAP provides 7 primary signal processing functions.
1.
The data processing input has a full 8x8 input crossbar mixer. This enables each input to be any ratio of
the eight input channels.
Two I
2
C programmable threshold detectors in each channel support automute.
2.
3.
Four soft bass and treble tone controls with
±
18 dB range, programmable corner frequencies, and 2nd
order slopes. In 8-channel mode, bass and treble controls are normally configured as follows:
a.
Bass and treble 1: channel 1 (Left), channel 2 (right), and channel 7 (center)
b.
Bass and treble 2: channel 3 (left surround) and channel 4 (right surround)
c.
Bass and treble 3: channel 5 (left back surround) and channel 6 (right back surround)
d.
Bass and treble 4: channel 8 (subwoofer)
4.
Individual channel and master volume controls. Each control provides an adjustment range of +18 dB to
–127 dB. This permits a total volume device control range of +36 dB to –127 dB plus mute. The master
volume control can be configured to control six or eight channels. The DAP soft volume and mute
update
interval is I
2
C programmable. The update is performed at a fixed rate regardless of the sample rate.
5.
8x2 output mixer (channels 1
6). Each output can be any ratio of any two signal processed channels.
6.
8x3 output mixer (channels 7 and 8). Each output can be any ratio of any three signal processed channels.
7.
The DAP maintains three sets of coefficient banks that are used to maintain separate sets of sample rate
dependent parameters for the tone controls in RAM. These can be set to be automatically selected for
one or more data sample rates or can be manually selected under I
2
C program control. This feature
enables coefficients for different sample rates to be stored in the TAS5028A and then select when needed.
