DESCRIPTION
The PL611-05 is a low-cost general purpose
frequency synthesizer and a member of PhaseLink’s
Programmable ‘Quick Turn Clock (QTC)’ family.
PhaseLink’s PL611-05 offers generating two system
clock frequencies of up to 35MHz form a 10-30MHz
fundamental crystal or a Reference clock source.
Cascading of the ICs to produce additional clock
frequencies is also supported.
