DESCRIPTION

The PL611s-26 is a general purpose frequency

product family. Designed to fit in a small 6-pin DFN

or 6-pin SOT package for high performance

applications, the PL611s-26 offers very low phase

noise, jitter, and power consumption, while offering

up to 2 clock outputs.. The Frequency Switching

(FSEL) capability of PL611s-26 allows for

programming two sets of frequencies, while the

power down feature of PL611s-26, when activated,

allows the IC to consume less than 10 A of power.

PL611s-26’s programming flexibility allows

generating any output using Reference input signal.
