TXM24M0004252BBCEO00T from TAE(Zhejiang Abel 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 | XTAL1 | passive | Crystal terminal connected to one side of the 24.000000 MHz fundamental-mode resonator (CL 8 pF, drive level 100 uW max) in the top-view drawing. |
| 2 | NC | unconnected | Pad with no internal connection drawn to the resonator in the top-view drawing; it is soldered for mechanical support. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the 24.000000 MHz resonator in the top-view drawing. |
| 4 | NC | unconnected | Pad with no internal connection drawn to the resonator in the top-view drawing; it is soldered for mechanical support. |
