DESCRIPTION
The PL611s-64 is a high performance low-cost general purpose frequency synthesizer that is designed to fit in a
small 2.5mmx2.0mm oscillator module for high performance, high frequency applications where the traditional 3 rd
overtone crystals are too large to fit the small form-factor packaging. The PL611s-64 offers the best phase noise
and jitter performance, smallest die size, and power consumption of any comparable device. PL611s-64
consumes very little power, but is capable of producing up to 100MHz, from a low-cost 25MHz crystal input.
