Universal hi-fi audio processor for TV TDA9859
FUNCTIONAL DESCRIPTION
The TDA9859 consists of the following functions:
• Source select switching block
• Loudspeaker channel with effect controls
• Two port outputs for general purpose
• I2C-bus control.
Source select switching block
The TDA9859 selects and switches the input signals from
three stereo or six mono sources MAIN, AUX and SCART
(see Fig.1) to the outputs SCART and loudspeaker
(crossbar-switching; Table 4). The main channel (LINE
outputs) is looped outside the circuit (from pins MOUT
R
and MOUTL to pins LINR and LINL), so signals can be
used as LINE output or a surround sound decoder can be
inserted.
Effect controls
‘Linear stereo’, ‘stereo with spatial effect (30% or 52%
anti-phase crosstalk)’ and ‘forced mono with or without
pseudo-stereoeffect’arecontrolledbythreebits.Amuting
of 85 dB is provided.
Loudspeaker channel
Volumecontrol is divided into volume control common and
volume control left/right. The common part
(−40 to +15 dB) controls the left and right channels
simultaneously;theleft/rightpart (−23 to 0 dB) controlsthe
volume of left and right channels independently. Treble
control provides a control range from −12 to +12 dB and
bass control from −12 to +15 dB. Extended bass control
can be provided by an external T-network (see Fig.1) from
−15 to +19 dB (in 2 dB steps).
2
C-bus control
I
All control settings are stored in subaddress registers.
Data transmission is simplified by auto-incrementing the
subaddresses. The on-chip Power-on reset sets the mute
bit to active, so both the SCART and the loudspeaker
outputs are muted.
Themutingcanbeswitchedoff by writing a ‘0’(non-muted)
into the mute control bits.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
