# 2520 32M 9PF 10PPM

**SST** · Crystals · SMD2520-4P

2520 32M 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 1 of the 2520 seam-sealed resonator, connected to one side of the 32 MHz crystal (CL 09 pF, Rr max 80 Ω). |
| 2 | GND | power_in | Pad 2 is marked GND in the connection diagram, tied to the lid/ground. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 2520 seam-sealed resonator, connected to the other side of the 32 MHz crystal (CL 09 pF, Rr max 80 Ω). |
| 4 | GND | power_in | Pad 4 is marked GND in the connection diagram, tied to the lid/ground. |

## CAD (KiCad official)

- Symbol: `2520 32M 9PF 10PPM`
- Footprint: `Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm`
- 3D model: SMD2520-4P (KiCad packages3D, STEP)
- 3D model files: `2520-32m-9pf-10ppm-etched.step` / `2520-32m-9pf-10ppm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2520-32m-9pf-10ppm.step` / `2520-32m-9pf-10ppm.glb` are the bare package body.
