CXA2095S
4. Notes on operation
When designing the board pattern for TV set, interference from around the power supply and GND should be
considered as the RGB and deflection signals output from the CXA2095S are DC direct connected.
Do not separate the GND patterns for each pin; a solid earth is ideal. Locate the power supply side of the by-
pass capacitor which is inserted between the power supply and GND as near to the pin as possible. Also,
locate the XTAL oscillator, ceramic oscillator and IREF resistor as near to the pin as possible, and do not wire
signal lines near this pin.
Drive the Y, external Y/color difference and external RGB signals at a sufficiently low impedance, as these
signals are clamped when they are input using the capacitor connected to the input pin.
The built-in capacitor receives the chroma signal, so apply a DC bias of about V
/2 externally and input the
CC
chroma signal at a sufficiently low impedance.
