SAMSUNG’s S3C2440A is
designed to provide hand-held devices and general applications with low-power, and high-performance microcontroller
solution in small die size. To reduce total system cost, the S3C2440A includes the following components.
There are many different (and often confusing) terms associated
with clock-based devices. This application note attempts
to clarify these terms, and hence serves as a comprehensive
reference on clock terminology. This application note can be
divided into two sections. The first section describes and distinguishes
between various clock sources available today.
The second section defines and distinguishes between various
parameters used to describe clocks. This section also provides methods of measuring some of these parameters.
