DESCRIPTION
The PL611s-08 is a low-power general purpose
frequency synthesizer and a member of PhaseLink’s
Programmable ‘Quick Turn Clock (QTC)’ family.
PhaseLink’s PL611s-08 can generate two system
clock frequencies of up to 75MHz from a 10MHz to
50MHz fundamental crystal or a 1MHz to 100MHz
Reference clock source. The PL611s-08 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.
