MEMS oscillator with HCSL output for PCIe clocking
Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without a dedicated LDO.
Package footprint and board layout notes
Housed in a 20-VFQFN with exposed pad, measuring 5.00 mm x 3.20 mm with a 0.90 mm seated height. The 0.50 mm pitch QFN demands a solder-paste stencil aperture reduction to avoid bridging on the outer rows.
This limits the part to indoor, office, or consumer equipment; it is not qualified for industrial outdoor cabinets, engine bays, or cold-chain storage.
