The 83PN187I 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 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 4th Generation FemtoClock® NG PLL technology, which delivers sub 0.5ps rms phase jitter. The 83PN187I defaults to 150MHz using a 25MHz crystal with 2 programming pins floating (pulled down/pulled up with internal pullup or pulldown resistors) but can also be set to 4 different frequency multiplier settings to support a wide variety of applications. The below table shows some of the more common application settings.
