8Y26000053 from TXC Corp, in a SMD2016-4P. 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 (pin 1 marked by the dot on the lid) of the 26.000000 MHz fundamental-mode unit, non-polarized and connected across to pin 3. |
| 2 | GND | power_in | Ground connection, shown as GND in the datasheet connection diagram (typically the lid/case ground). |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 26.000000 MHz fundamental-mode unit, non-polarized and connected across to pin 1. |
| 4 | GND | power_in | Ground connection, shown as GND in the datasheet connection diagram (typically the lid/case ground). |
