7B011059R01 from HD, in a SMD3225-4P. 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 | passive | Crystal terminal for the 11.0592MHz fundamental-mode resonator (20pF load capacitance, 100 ohms max resonance resistance). |
| 2 | GND | power_in | Ground pad, connected to GND in the internal view connection. |
| 3 | CRYSTAL | passive | Second crystal terminal for the 11.0592MHz resonator, used with pin 1 (20pF load capacitance). |
| 4 | GND | power_in | Ground pad, connected to GND in the internal view connection. |
