Preliminary specification
TV and VTR stereo/dual sound processor
with integrated filters and I
2
C-bus control
TDA8417
De-matrix and de-emphasis
Depending on the results of the identification circuit (mono, stereo or dual sound) the AF signals at the inputs E1 and E2
are converted to the signals at E1* and E2* as listed in Table 1.
Table 1
Transmitter status
(1)
Note
1.
L = left channel signal;
R = right channel signal;
A = first sound channel signal;
B = second sound channel signal
This section of the circuit also performs the de-emphasis (50
μ
s time constant) with a high degree of accuracy.
AF switch
The AF switch is used to switch to either the internal sound sources (E1* or E1* and E2*) or, to the external sound source
(E3 and E4) and is controlled via the I
2
C-bus.
Source selector
The source selector is used to connect the outputs from the AF switch to the outputs A1 to A4 as illustrated by Table 5.
The selector is controlled via the I
2
C-bus.
Muting
In this mode the AF outputs A1 to A4 are muted, and the identification circuit is deactivated (mono). The muting is active
after power-on reset or as a result of user control (via the mute input and bit CR3 of the control byte of the mute and port
control register; see Table 4).
Sound mute
If the switch register is set to (00) hex, (sound mute) only the AF outputs are muted, the identification circuit is still active
and can be read (status register) via the I
2
C-bus.
