TDA2595
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 posite 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...
