TZ1917B 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 | IN/OUT | passive | Crystal terminal (IN/OUT) of the 12.8 MHz fundamental-mode crystal, 20 pF load capacitance, 100 uW max drive level. |
| 2 | GND | power_in | Ground pad, connected to GND per the pin connection table. |
| 3 | IN/OUT | passive | Second crystal terminal (IN/OUT) of the 12.8 MHz crystal, interchangeable with pin 1. |
| 4 | GND | power_in | Ground pad, connected to GND per the pin connection table. |
