DEVICE DESCRIPTION
The
ZX FV4089 is a DC restoring circuit and
low-distortion video amplifier. It is specially designed
to provide brightness level stability as a ‘black-level
clamp’ in video systems with very low distortion and
low power consumption
.
A high fidelity video amplifier is combined with a
sample-hold switch circuit using an external coupling
capacitor to provide level-shifting of the video output
such thata time-gated sample ofthe waveform is setto
be equal to an external reference voltage (usually zero
voltage).
A buffered TTL/CMOS logic input signal
controls the switch.
The gain is set externally by two resistors.
In a typical application, the sample-hold circuitis gated
on during part of the back-porch interval of an analog
video waveform.
Then the video waveform is
stabilised for the remainder of the line-scan interval.
