TDA2595

INTEGRATED CIRCUITS DATA SHEET TDA2595 Horizontal combination Product specification File under Integrated Circuits, IC02 March 1987 Philips Semiconductors Product specification Horizontal combination 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 TDA2595 Output stage for vertical sync pulse or composite sync depending on the load; both are switched off at muting ϕ1 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 detector ϕ3 ϕ1 gating pulse controlled by coincidence detector ϕ3 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 switc...
