Description
The 8N3PF10VA-159I 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 programmability 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.
The 8N3PF10VA-159I generates four default frequencies 100MHz or 156.25MHz from a 25MHz fundamental mode crystal, or 212.5MHz or 106.25MHz from a 26.5625MHz fundamental mode crystal. The output frequency is selected by FSEL0 and FSEL1 pins.
