Audio video input processor
The supported crystal/external clock frequencies are 27 MHz and 13.5 MHz. The crystal
oscillator is followed by a selectable divide-by-two frequency divider giving three available
clock frequencies, as shown in
Table 25
.
The crystal specification is:
Package: surface mount.
Accuracy: (
±
50 ppm).
Temperature: (
±
50 ppm).
Operating temperature range:
20 to +70
o
C.
Load capacitance: 30 pF.
