Filter Cut-Off
A resistor RF connected between this input and ground determines the input filter characteristic
Increasing RF increases the filter 358 MHz color burst attenuation See the graph showing filter
characteristics
2
Set Detect Level
A resistor RLV connected between pin 2 and ground determines the value of the minimum signal
which will trigger the loss of signal output on pin 10 The relationship is VPMIN e 075 RLV
RSET where VPMIN is the minimum detected sync pulse amplitude applied to pin 4 See
characterization curve
3
Composite Sync
This output replicates all the sync inputs on the input video
Output
4
Filter Input
The filter is a 3 pole active filter with a gain of 2 designed to produce a constant phase delay of
nominally 260 ns with signal amplitude Resistor RF on pin 1 controls the filter cut-off An internal
clamp sets the minimum voltage on pin 4 at 155V when the input becomes low impedance Above
the clamp voltage an input current of 1
mA charges the input coupling capacitor With loss of signal
the current source switches to a value of 10
mA for faster signal recovery
5
Vertical Sync
The vertical sync output is synchronous with the first serration pulse rising edge in the vertical
interval of the input signal and ends on the trailing edge of the first equalizing Output pulse after
Output
the vertical interval It will therefore be slightly more than 3H lines wide
