Platform Clock General Introduction

10.1.1

Description

®
Intel Quark™ SoC X1000 implements full integrated clocking mode as the default
platform clock solution. In the full-clock integration mode, a 25 MHz crystal oscillator
provides the input clock to the Intel
and SoC generates the output clocks that are required by all the platform components.
