The PL611-20 is a low-cost general purpose frequency synthesizer and a member of PhaseLink’s Factory
Programmable ‘Quick Turn Clock (QTC)’ family. PhaseLink’s PL611-20 product family can generate any output
frequency up to 200 MHz from fundamental crystal input between 10 MHz - 30 MHz, or a 3rd overtone crystal of
up to 75Mhz.
