Splet09. dec. 2024 · The Basics of Stitching Vias in a PCB. Stitching vias are simple structures: they are a periodic array of vias that are generally grounded across the PCB stackup. In this way, they are making connections between ground nets on multiple layers. Note that there is one usage of via arrays that involves power connections across layers (see below). Splet– XTAL OUT to ground: 2pF – XTALIN to XTALOUT: 0.5pF These values are slightly package dependent. • Reduce the parasitic capacitance between XTAL IN and XTAL OUT pins by routing them as far apart as possible • A ground area should be placed under the crystal oscillator area. This ground land should be connected to the oscillator ground.
