Notes : 1. Width of vertical blanking pulse on SSC output is proportional to the frame flyback time, the switching level is VCC2 - 2VBE and

the other input of the comparator is tied to the frame amplifier output. Application circuit uses the frame flyback generator .

2. An RC network is connected to this input. Typical value for the resistor is 27kΩ and 220pF for the capacitor. A different time
constant for RC changes the delay between the middle of the line synchro pulse and the leading edge of the burst key pulse but
also the duration of the burst key pulse.

GENERAL DES CRI PTI O N

The TDA8214B performs all the video and power
functions required to provide signals for the line
driver and frame yoke.

It contains:

- A synchr onization separat or

- 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 protect ed)

- An open collector output for the line driver

- A line phase detector and a voltage control osci l­lator

- A super sandcastle generator

- Video identification output.

The slice level of sync-separat ion is f ixed by value
of the external resistors R1 and R2. V
internally fixed voltage.

The sync-pulse allows the discharge of the capaci­tor by a 2 x I current. A line sync-pulse is not able
to discharge the capacitor under V

The sync-pulse drives the current in the compara­tor. 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 c urrent for the part of the
signal on pin 13 greater t han to V C and a negative
current for the other part. When t he line flyback and
the video signal are synchronized, the output of the

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.

Frame output amplifier

This amplifier is able to drive directly the frame
yoke. Its output is short circuit and overload pro­tected; it contains also a thermal protect ion.

The frame blanking is detected by the frame fly­back generator. When the output voltage of the
frame amplifier exceeds V

a comparator which compares the input line flyback
pulse to an internal ref erence. The burst gate pulse
position is fixed by the external RC network
(Pin 14). It is referenced to the middle of the line

This stage will detec t the coincidenc e bet ween th e

line sync pulse (if present) and a 2µs sampling
pulse. This 2µs pulse is positionned at the center
of line sync pulse when the phase loop is locked.
This sampled detection is stored by an external
capacitor Pin 8.

The identification output level is high when video
