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

1

phase control between horizontal sync and oscillator

• 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

3

• 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
