Horizontal combination TDA2595

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 Ω)
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
•ϕ
phase control between horizontal sync and oscillator
1
Coincidence detector ϕ3 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 detectorϕ3
•ϕ1 gating pulse controlled by coincidence detector ϕ
Mute circuit depending on TV transmitter identification
•ϕ2 phase control between line flyback and oscillator; the slicing levels for ϕ2 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
