2520 24M 9PF 10PPM from SST, in a SMD2520-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XTAL1 | passive | Crystal terminal connected to one side of the resonator (24.000MHz, 9pF load); pad 1 has the chamfered corner marking. |
| 2 | GND | power_in | Connected to ground (lid/case) per the connection diagram; not an active crystal terminal. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the resonator (24.000MHz, 9pF load). |
| 4 | GND | power_in | Connected to ground (lid/case) per the connection diagram; not an active crystal terminal. |
