Figure 1 : Synchronization Separator Circuit
GENERAL DESCRIPTIONThe TDA8214B performs all the video and power
functions required to provide signals for the line
driver and frame yoke.
It contains: A synchronization separator An integrated frame separator without external
components A saw-tooth generator for the frame A power amplifier for direct drive of frame yoke
(short circuit protected) An open collector output for the line driver A line phase detector and a voltage control oscil-
lator A super sandcastle generator Video identification output.
The slice level of sync-separation is fixed by value
of the external resistors R1 and R2. VR is an
internally fixed voltage.
The sync-pulse allows the discharge of the capaci-
tor by a 2 x I current. A line sync-pulse is not able
to discharge the capacitor under VZ/2. A frame
sync-pulse permits the complete discharge of the
capacitor, so during the frame sync-pulse Q3 and
Q4 provide current for the other parts of the circuit.
Figure 2 : Frame Separator
TDA8214B5/9
Figure 3 : Line OscillatorThe oscillator thresholds are internally fixed by
resistors. The discharge of the capacitor depends
on the internal resistor R4. The control voltage is
applied on resistor R5.
Figure 4 : Phase ComparatorThe sync-pulse drives the current in the compara-
tor. The line flyback integrated by the external net
work gives on pin 13 a saw tooth, the DC offset of
this saw tooth is fixed by VC. The comparator
output provides a positive current for the part of the
signal on pin 13 greater than to VC and a negative
current for the other part. When the line flyback and
the video signal are synchronized, the output of the
comparator is an alternatively negative and positive
current. The frame sync-pulse inhibits the compa-
rator to prevent frequency drift of the line oscillator
on the frame beginning.
Figure 5
Line output (Pin 17)It is an open-collector output. The output positive
pulse time is 29μs for a 64μs period.
The oscillator thresholds are internally fixed by
resistors. The oscillator is synchronized during the
last half free run period. The input current during
the charge of the capacitor is less than 100nA.
