The LTC6951IUHF#PBF is a single-circuit PLL clock synthesizer that accepts a clock input and produces up to five outputs in CML or LVDS format, with a maximum output frequency of 2.5 GHz.
The supply range is 3.15V to 3.45V, so a nominal 3.3V rail sits comfortably inside the window.
The exposed pad also serves as the low-inductance return path for the PLL charge pump — a cold solder joint under the pad will degrade phase noise.
Yes. The supply voltage range is 3.15V to 3.45V, so a nominal 3.3V rail is within tolerance.
The #PBF suffix indicates ROHS3 compliant finish. The base part number LTC6951IUHF is the same silicon; the #PBF variant is the lead-free version. Pin compatibility is identical — the package and pinout did not change.
