Description

Inserts a pulse slightly larger than BF

on both ends.

BF

BFG

VTH is at 2.5V. Input a pulse with an

amplitude larger than VTH ± 0.5V.

10 BF

5V

0V

Inputs BF (burst flag) pulse.

During analog burst, the input pulse

AVCC

smoothens the waveform.

the envelope of the analog burst

waveform.

AGND

Inputs CT (chroma titler) pulse.

This signal prevents the application

of chroma suppress during the titler

signal period.
