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 Rew determines the gain of the EW output stage. Resistor Rc sets the reference current for both the vertical

sawtooth generator and the geometry processor. The preferred value of Rc = 39 kΩ results in a reference current of 100

µA (V

ref = 3.9 V).

The value of Rew is given in the following equation:

Example: If Vref = 3.9 kΩ, Rc = 39 kΩ and Vscan = 120 V then Rew = 68 kΩ
