10 to 200 MHz DLL-based frequency multiplier
Overview
DLL-based frequency multiplier is a simple to configure and operate block, combining, small area and low current consumption. Block wakes up in “pass-through” mode with redirecting input reference frequency to the output. After being configured and enabled the block waits until DLL locks and then switches output clock signal CLK_OUT to higher frequency. Disabling block switches it back to “pass-through” mode. Any mode switching is glitch-protected.
