!Note
VCO circuits are used in TVs and audio equipment,
because the signals need to be processed in
synchronization with pilot signals transmitted from
broadcasting stations. Oscillation circuits, such as LC
and RC, were previously often used, but CERALOCK
now widely used as well, because they require no
adjustment and have superior stability over the older
type circuit.
Resonators, for VCO applications, are required to have a
wide variable frequency range. We supply CERALOCK
devices with specially designed ceramic materials for
VCO applications.
Application to TV Horizontal Oscillation
Circuits
Fig. 6-18 to 6-20 show application examples of horizontal
oscillation circuits.
Fig. 6-18 and 6-19 are examples of NTSC system
(FH=15.734kHz) and Fig. 6-20 is for PAL system
(FH=15.625kHz).
