DEFLECTION PROCESSOR FOR MULTISYNC MONITORS KB2511B

The KB2511B also includes a lock/unlock identification block which senses in real time whether PLL1 is locked or
not on the incoming horizontal sync signal. The resulting information is available on Hlockout (see sync processor).
The block function is described in figure 12.
When PLL1 is unlocked, It forces Hlockout to leave high.
The lock/unlock information is also available throw I
2
C read.
PLL2
The PLL2 ensures a constant position of the shaped flyback signal in comparism with the sawtooth of the VCO
(figure 12).
The phase comparator of PLL2 (phase type comparator) is followed by a charge pump(typical output cur-
rent:0.5mA).
The flyback input is composed of an NPN transistor. This input must be current driven. The maximum
recommanded input current is 5mA (see figure 13).
The dury cycle is adjustable through I
2
C from 30% to 60%. For startup safe operation, initial duty cycle (after power
on reset) is 60% in order to avoid having a too long conduction period of the horizontal scanning transistor. The
maximum storage time(Ts MAX.) is (0.38T
H
-T
FLY
/2). Typically, T
FLY
/TH is around 20% which means that Ts max
is around 28% of T
H
.
