PL902XXX Datasheet, PDF (1/10 Pages) Micrel Semiconductor – Lowest power and smallest programmable jitter attenuator

PL902xxx
Revision 1.1
General Description
The PL902xxx series is a low-power, small form-factor,
high-performance OTP-based device and a member of
Micrel’s JitterBlocker, factory programmable jitter
attenuators. The JitterBlocker product family cleans any
deterministic jitter, thereby improving the peak-to-peak
jitter, accumulated jitter, and even the phase noise. The
PL902xxx is capable of reducing thousands of
picoseconds of period jitter in a clock to a level below
100ps peak-to-peak, making that clock usable for many
more applications.
The PL902xxx operates on a single 2.5V or 3.3V supply,
consumes little power, and is housed in a small SOT23
package for a broad range of applications. Programmable
I/O pins can be configured as output enable (OE),
configuration select (CSEL), power down (PDB) input, or
CLK1 (2) output. The power down feature of PL902xxx,
when activated, allows the IC to consume less than 10µA
of power, while its programming flexibility allows filtering of
any clock frequency, up to 200MHz.
