Preliminary specification
PAL/NTSC/SECAM decoder/sync processor
TDA9160
QUALITY SPECIFICATION
Quality level according to URV 4-2-59/601.
Test and application information
EW output stage
In order to obtain the correct tracking
of the vertical and horizontal EHT
correction, the EW output stage
should be configured as illustrated in figure 8.
Note to
Fig.8
Resistor R
ew
determines the gain of the EW output stage. Resistor R
c
sets the reference current for both the vertical
sawtooth generator and the geometry processor. The preferred value of R
c
= 39 k
results in a reference current of 100
μ
A (V
ref
= 3.9 V).
The value of R
ew
is given in the following equation:
Example: If V
ref
= 3.9 k
, R
c
= 39 k
and V
scan
= 120 V then R
ew
= 68 k
