Note 3. To ensure safe locking of the horizontal oscillator , one of the following procedures is required :
a) Search mode starts always from f
. Then the PLL1 filter components are a 3.3nF
min
capacitor from Pin26 to GND in parallel with an 8.2kΩ resistor in series with a 47nF
capacitor.
b) Search mode starts either from f
min
or f
with HPOS in m iddle position (I
max
HPOS
= 60µA).
Then the PLL1 filter components are a 1.5nF capacitor from Pin26 to GND in parallel
with a 27kΩ resistor in series with a 47nF capacitor.
c) After locking is achieved, HPOS can be operated in the normal way
Note 4. Loading of HPLL1 (Pin26) is not allowed.
Note 5. Oscillator frequency is f
when no sync signal is present (no continuous blanking at Pin16).
min
Note 6. V oltage at HPPL1 (Pin26) is fed to HBUF (Pin27) via a buffer. Disturbances caused by hori-
zontal sync are removed by an internal sample–and–hold circuit.
