Filter PLL
The on board reference filter produces a phase shift which is
measured and applied to an internal filter PLL. This capacitor
connected to this pin stores the phase correction voltage for the PLL
which sets the 90
°
phase correction reference for the rest of the on
chip filters.

Video Input 1 and 2
Accepts ac coupled 1.0 Vpp composite video input usually from a
source generated inside the TV and an external video source.
The series coupling capacitor also functions as the storage capacitor
for the clamp voltage for the input circuit. It is necessary to return the
input of this capacitor to ground through a dc low impedance to enable
this clamp function. R = 50 to 100
is acceptable.

Decoder ACC
The Decoder ACC pin provides access to the internal chroma decoder
automatic gain control amplifier. The ACC capacitor filters the feedback
loop of this amplifier.
During PIP burst gate time a voltage proportional to the burst gate
magnitude is stored on the capacitor connected to this pin to
compensate for input chroma level variation and provide a constant
U and V output level to the A/D conversion stage.
