Suzhou Liming Elec · Crystals · SMD2520-4P

2520-32-8-10-10 from Suzhou Liming Elec, 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 CRYSTAL_1 passive One of the two crystal signal terminals; the datasheet does not state its individual function, only that the crystal's level of drive is 10 to 200 µW and shunt capacitance Co is at most 3.0 pF.
2 GND power_in Connected to the metal cover, and the datasheet instructs that it be connected to ground.
3 CRYSTAL_2 passive The second crystal signal terminal; the datasheet does not state its individual function, only that the crystal's level of drive is 10 to 200 µW and shunt capacitance Co is at most 3.0 pF.
4 GND power_in Connected to the metal cover, and the datasheet instructs that it be connected to ground.
