Yajingxin · Crystals · SMD3225-4P
TAXM8M4RDBCCT2T from Yajingxin, 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 (chamfered pad-1 corner) for the 8.000000 MHz fundamental-mode resonator, 10 pF load capacitance ±10%, drive level 10 uW. |
| 2 | GND | power_in | Ground connection (marked GND in the connection diagram), typically tied to the lid/case. |
| 3 | XTAL2 | passive | Second crystal terminal, diagonal to pin 1, of the 8.000000 MHz resonator with max equivalent resistance 250 Ω. |
| 4 | GND | power_in | Ground connection (marked GND in the connection diagram), typically tied to the lid/case. |
