PL904xxx
Revision 1.0
General Description
The PL904xxx series is a small form-factor, high
performance, programmable 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 PL904xxx is capable of reducing
multiple pico seconds of phase jitter in a clock to a level
below 0.5ps_RMS in most cases, making that clock usable
for many more applications.
The PL904xxx 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 250MHz can be filtered and
frequency translation allows for output clock frequencies
up to 850MHz. The input clock can be single-ended or
differential.
