DESCRIPTION

The PL611-07 is a low-cost general purpose frequency synthesizer and a member of PhaseLink’s Programmable ‘Quick Turn Clock (QTC)’ family. PhaseLink’s PL611-07 offers generating two system clock frequencies of up to 75MHz form a 10-30MHz fundamental crystal or a Reference clock source. One clock output can be programmed to operate as OE or be used as a Reference output. Cascading of the ICs to produce additional clock frequencies is also supported.
