Datasheet
Description
The 83PR226I-01 is a programmable LVPECL synthesizer that is
“forward” footprint compatible with standard 5mm x 7mm oscillators.
Forward footprint compatibility means, a board is designed to
accommodate the crystal oscillator interface, and the optional
control pins are also fully compatible with a canned oscillator
footprint (the canned oscillator will drop onto the 10-VFQFN footprint
for second sourcing purposes). This capability provides designers
with programability and lead time advantages of silicon/crystal based
solutions, while maintaining compatibility with industry standard
5mm x 7mm oscillator footprints for ease of supply chain
management. Oscillator-level performance is maintained with IDT’s
3^rd generation FemtoClock^® PLL technology, which delivers sub 1ps
RMS phase jitter.
The 83PR226I-01 defaults to 125MHz using a 25MHz crystal with all
4 of the programming pins floating (pulled HIGH with internal pullup
resistors), but can be also be set to 15 different frequency multiplier
settings to support a wide variety of applications. The table below
shows some of the more common application settings.
