Notes : 1. Width of vertical blanking pulseon SSC output is proportional to the frame flyback time, the switching level is VCC2-2VBEand

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 is27kΩ and 220pF for the capacitor. A different time
constant forRC changes the delaybetween the middle of the line synchro pulse and theleading edge of the burst key pulse but
also the duration of the burst keypulse.

GENERALDESCRIPTION

The TDA8215B performs all the video and power
functions required to provide signals for the line
driverand frame yoke.

It contains:

- A synchronizationseparator

- An integrated frame separator without external
components

- A saw-tooth generator for the frame

- A power amplifier for direct drive of frame yoke
(short circuitprotected)

- An open collector output for the line darlington
drive

- Video identificationoutput.

The slice level of sync-separationis fixedby value
of the external resistors R1 and R2. VR is an
internallyfixed voltage.

The sync-pulseallows the dischargeof the capaci­tor by a 2 x I current.A line sync-pulseis not able
to discharge the capacitor under V

This stage will detect thecoincidencebetween the

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
signalis present.
