Frequency Transitions
A key feature of the
AV9155
is its ability to provide smooth,
glitch-free frequency transitions on the CPU and 2XCPU clocks
when the frequency select pins are changed. These frequency
transitions do not violate the Intel 486 specification of less
than 0.1% frequency change per clock period.
Using an Input Clock as Reference
The
AV9155
is designed to accept a 14.318 MHz crystal as the
input reference. With some external changes, it is possible to
use a crystal oscillator or clock input. Please see application
note AN04 for details on driving the
AV9155
with a clock.
