Datasheet Microchip PL903 — Datenblatt

PL903xxx Revision 1.0 General Description Features The PL903xxx series is a small form factor, high
performance OTP-base device and a member of Micrel’s
JitterBlocker, factory programmable jitter attenuators. The
JitterBlocker product family cleans deterministic jitter by
attenuating spurious components in the phase noise,
thereby improving the phase jitter and the overall phase
noise. The PL903xxx is capable of reducing multiple pico
seconds of phase jitter in a clock to a level below 1psRMS,
making that clock usable for many more applications. The PL903xxx operates on a single 2.5V or 3.3V supply
and is housed in a small QFN package for a broad range
of applications.
Input clock frequencies up to 200MHz can be filtered and
frequency translation allows for output clock frequencies
up to 840MHz. Datasheets and support documentation are available on
