CJ15-160000810A20 from Changjing, 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 (chamfered pad, bottom-right in bottom view) wired to the crystal symbol; 16.000MHz fundamental mode, 8pF load capacitance, 100ohms max resonance resistance. |
| 2 | NC | unconnected | Pad not wired to the crystal symbol in the bottom-view drawing; no function is stated in the datasheet. |
| 3 | XTAL2 | passive | Second crystal terminal (top-left in bottom view) wired to the crystal symbol; 16.000MHz fundamental mode, drive level <100µW. |
| 4 | NC | unconnected | Pad not wired to the crystal symbol in the bottom-view drawing; no function is stated in the datasheet. |
