TZ0356E from TST, 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 | GND | power_in | Pin #1 is connected to GND per the pin connection table, and it is a ground/lid pad of the 3.2x2.5 mm crystal. |
| 2 | GND | power_in | Pin #2 is connected to GND per the pin connection table, and the datasheet notes the inner side of Pin#2/Pin#3 is the XTAL blank mounting pad. |
| 3 | IN/OUT | passive | Pin #3 is the crystal IN/OUT terminal for the 40.000000 MHz fundamental-mode crystal with a 11 pF load capacitance. |
| 4 | GND | power_in | Pin #4 is connected to GND per the pin connection table. |
