GENERAL DESCRIPTION
The TDA2595 is a monolithic integrated circuit intended for use in colour television receivers.
Features
·
Positive video input; capacitively coupled (source impedance
<
200
W
)
·
Adaptive sync separator; slicing level at 50% of sync amplitude
Internal vertical pulse separator with double slope integrator
·
Output stage for vertical sync pulse or composite sync depending on the load; both are switched off at muting
·j
1
phase control between horizontal sync and oscillator
·
j
3
for automatic time-constant switching; overruled by the VCR switch
·
Time-constant switch between two external time-constants or loop-gain; both controlled by the coincidence detector

2
control and horizontal blanking can be set
separately
·
Burst keying and horizontal blanking pulse generation, in combination with clamping of the vertical blanking pulse
(three-level sandcastle)
·
Horizontal drive output with constant duty cycle inhibited by the protection circuit or the supply voltage sensor
·
Detector for too low supply voltage
·
Protection circuit for switching off the horizontal drive output continuously if the input voltage is below 4 V or higher
than 8 V
·
Line flyback control causing the horizontal blanking level at the sandcastle output continuously in case of a missing
flyback pulse
·
Spot-suppressor controlled by the line flyback control
