Functionality
(Using 14.318 MHz input. All frequencies in MHz.)
CLOCK#2 CPU and 2XCPU
Functionality - AV9155C-02
CLOCK#2 CPU and 2XCPU
Frequency Transitions
A key feature of the AV9155C 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 14.318 MHz input. All frequencies in MHz.)

Using an Input Clock as Reference
The AV9155C 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 AV9155C with a clock.
