DESCRIPTION
The PL611-25 is a low-cost general purpose
frequency synthesizer and a member of PhaseLink’s
Factory Programmable ‘Quick Turn Clock (QTC)’
family. PhaseLink’s PL611-25 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.
