概要
説明
The 83PN156I is a programmable LVPECL synthesizer that is "forward" footprint compatible with standard 5mm x 7mm oscillators. The device uses Renesas' 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 Renesas' 4th Generation FemtoClock™ NG PLL technology, which delivers sub 0.5ps rms phase jitter. The 83PN156I defaults to 156.25MHz using a 25MHz crystal with 2 programming pins floating 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.
