CJ16-260000710B20 from Changjiang Electronics Tech (CJ), 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 connected to the quartz element, diagonal to pin 3 in the connection diagram, for a 26MHz fundamental-mode crystal with 7pF load capacitance. |
| 2 | GND | power_in | Ground pad, labeled GND in the connection diagram, diagonal to pin 4. |
| 3 | XTAL2 | passive | Crystal terminal connected to the quartz element, diagonal to pin 1 in the connection diagram, with drive level below 100µW. |
| 4 | GND | power_in | Ground pad, labeled GND in the connection diagram, diagonal to pin 2. |
