PLL IC for LCD Monitor/Projector
CXA3266Q
Description
The CXA3266Q is a PLL IC for LCD monitors/
projectors with built-in phase detector, charge pump,
VCO and counter.
The various internal settings are performed by
serial data via a 3-line bus.
Applicable LCD monitor/projector resolution are
NTSC, PAL, VGA, SVGA, XGA, SXGA and UXGA
etc.
The CXA3266Q is the same package as the
previous CXA3106Q and CXA3106AQ. They have
the same pin configuration excluding Pin 38.
