X1E0000210129 from Seiko Epson, 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 | XTAL1 | passive | Crystal terminal #1 of the TSX-3225 (12-48 MHz range per 16.000-48.000 MHz nominal; load capacitance CL 7 pF to ∞, drive level 200 µW Max.). |
| 2 | GND | power_in | Connected internally to the metal case/lid; the datasheet says to connect it to ground. |
| 3 | XTAL2 | passive | Crystal terminal #3 of the TSX-3225, the second crystal terminal (ESR 60 Ω Max. for 16.0-21.0 MHz, 40 Ω Max. for 21.0-48.0 MHz). |
| 4 | GND | power_in | Connected internally to the metal case/lid; the datasheet says to connect it to ground. |
