Functional Description
Introduction
This product is a dual monolithic continuous time video filter
designed for reconstructing the luminance and chrominance
signals from an S-Video D/A source. Composite video out-
put is generated by summing the Y and C outputs. The chip
is intended for use in applications with AC coupled input and
AC coupled outputs. (See Figure 1)
The reconstruction filters approximate a 4th-order Butter-
worth characteristic with an optimization toward low over-
shoot and flat group delay. Y, C, and CV outputs are capable
of driving 2V
pp
into AC coupled 150
to 35pF of load capacitance at the output pin.
video loads, with up
All channels are clamped during sync to establish the appro-
priate output voltage swing range. Thus the input coupling
capacitors do not behave according to the conventional RC
time constant. Clamping for all channels settles to less than
10mv within 5ms of a change in video input sources.
In most applications the input coupling capacitors are 0.1μF.
The Y and C input typically sinks 1μA during active video,
which nominally tilts a horizontal line by about 2mV at the Y
output. During sync, the clamp typically sources 20μA to
restore the DC level. The net result is that the average input
current is zero.
Any change in the input coupling capacitor’s value will
inversely alter the amount of tilt per line. Such a change will
also linearly affect the clamp response times.
This product is robust and stable under all stated load and
input conditions. Capacitive bypassing VCC directly to
ground ensures this performance.
Luminance (Y) I/O
The luma input is driven by either a low impedance source of
1V
P-P
or the output of a 75
terminated line. The input is
required to be AC coupled via a 0.1μF coupling capacitor
which allows for a settling time of 5ms. The luma output is
capable of driving an AC coupled 150
1V
pp
into a 75
load. Up to 35pF of load capacitance
(at the output pin) can be driven without stability or slew
issues. The output is AC coupled with a 400μF or larger AC
coupling capacitor.
