DESCRIPTION
The PL611s-06 is a low-power general purpose frequency synthesizer and a member of PhaseLink’s Programmable ‘Quick Turn Clock (QTC)’ family.
PhaseLink’s PL611s-06 can generate two system clock frequencies of up to 35MHz from a 10MHz to 30MHz fundamental crystal or a 1MHz to 100MHz Reference clock source.
The PL611s-06 offers the best phase noise and jitter performance, and power consumption of its rivals.
Cascading of the ICs to produce additional clock frequencies is also supported.
