DESCRIPTION
The PL611s-02 is a low-power, small form factor,
high performance OTP-base programmable
frequency synthesizer and a member of PhaseLink’s
PicoPLL Factory Programmable ‘Quick Turn Clocks.
Designed to fit in a small DFN, SC70, or SOT23
package for a broad range of applications, the
PL611s-02 offers the best phase noise and jitter
performance, and power consumption of its rivals. .
In addition, one programmable I/O pin can be
configured as Output Enable (OE), Frequency
switching (FSEL), Power Down (PDB) input, or CLK1
(F

/2) output. The power down
feature of PL611s-02, when activated, allows the IC
to consume less than 10 A of power, while its
programming flexibility allows generating any output,
up to 200MHz using a low-cost crystal or reference
input.
