30-200 MHz DLL-based frequency multiplier

Overview

055TSMC_DLL_01 is a frequency multiplier that combines low phase jitter of clock signal, small area and low current consumption. Block wakes up in “pass-through” mode and passes the input signal to the output. Once 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 into “pass-through” mode. Any mode switching is glitch-protected.
