General Description
The PL611s-02 is a low-power, small form factor, high
performance OTP-base programmable frequency
synthesizer and a part in the PicoPLL Factory
Programmable Quick Turn Clocks family.
Designed to fit in a small DFN or SOT-23 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 (F
SEL
), Power
Down (PDB) input, or CLK1 (F

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

† Notice:
Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended
periods may cause permanent damage to the device and affect product reliability. These conditions represent a stress
rating only, and functional operations of the device at these or any other conditions above the operational limits noted
in this specification is not implied. *Operating temperature is guaranteed by design. Parts are tested to commercial
grade only.
