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

• Lowest-power, smallest programmable jitter attenuator

• Input frequency up to 200MHz

• Output frequency up to 840MHz

• Jitter attenuation 20dB at 3MHz spur frequency

• Additive phase jitter or phase jitter floor:

− 55fs for 1.875MHz to 20MHz

− 251fs for 12kHz to 20MHz

• Single ended CMOS input

• One differential or two single ended outputs. Output

logic types supported are LVPECL, LVDS, HCSL and

LVCMOS (single ended or differential).

seconds of phase jitter in a clock to a level below 1ps_RMS

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.

• Operating temperature range from –40°C to +85°C

• Available in 24-pin QFN RoHS-compliant package.

− PL902xxx: LVCMOS, period jitter cleaning.

− PL904xxx: Differential input, two differential outputs,
