6-2. Each IC Description

6-2-1. PLL IC CXA3106Q (QX028) for RGB Signals

A configuration of CXA3106Q is shown in Fig. 6-2-1.

The PLL IC of CXA3106Q is an IC with high perfor-

mance and low jitter, and can generate the clock signal

synchronized with the horizontal sync signal of max. 120

MHz.

The VCO, phase comparator, loop filter and frequency

dividing circuit are built in the IC, so the IC can generate

the clock signal by itself.
