The 83PR226I-01 is a programmable LVPECL synthesizer that is "forward" footprint compatible with standard 5mm x 7mm oscillators. Forward footprint compatibility means that a board designed to accommodate the crystal oscillator interface and the optional control pins is 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 3rd 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 below table shows some of the more common application settings.
