DESCRIPTION

The PL611-01 is a low-cost general purpose frequency synthesizer and a member of PhaseLink’s Factory Programmable ‘Quick Turn Clock (QTC)’ family. PhaseLink’s PL611-01 product family offers the versatility of using a single Crystal or Reference Clock input and producing up to three different system clocks. They 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, or a Reference clock input of up to 200 MHz. Cascading of the ICs to produce additional clock frequencies is also supported.
