ILA8362ANS (8A)
Demodulation and array/matrix mode is switched
depending on input signal standard.
and brightness controls operate on internal and external
signals.
When applying to output 21 voltage of more then 4 V
there may be possibility of immediate application of
RGB-signals to RGB-outputs.
The circuit can co-operate with the SECAM add-on
decoder ILA8395.
Outputs signal amplitude at nominal settings and input
conditions is 2 V from white to black.
The communication between the two ICs is achieved via
pin 32. The ILA8362ANS supplies the reference signal
(4.43 MHz) for the calibration system of the ILA8395,
identification of the colour standard is via the same
connection.
Presence of automatic stabilisation of black current
enables to eliminate further settings of dark level during
operation. This circuit is a backfeed loop, operates during
four line periods, which precede the end of the blanking
frame pulse and stabilises black current of each of RGB-
channels in sequence and independently.
RGB output circuit
The colour difference signals are matrixed with the
luminance signal to obtain the RGB signals. The contrast
