The IDT83PN15639I is a programmable LVPECL synthesizer that is "forward" footprint compatible with standard 5mm x 7mm oscillators. The device uses IDT's fourth generation FemtoClock® NG technology for an optimum of high clock frequency and low phase noise performance. Forward footprint compatibility means that a board 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 4th Generation FemtoClock® NG PLL technology, which delivers sub 0.2ps rms phase jitter. The IDT83PN15639I defaults to 156.25MHz using a 25MHz crystal but can also be set to one of four different frequency multiplier settings to support a wide variety of applications. The table below shows some of the more common application settings.
