TZ1689A 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 connection table lists #1 as GND; the datasheet notes the inner side of Pin#1 and Pin#4 is an XTAL blank mounting pad. |
| 2 | GND | power_in | Pin connection table lists #2 as GND. |
| 3 | IN/OUT | passive | Crystal terminal, listed as IN/OUT in the pin connection table, for the 26 MHz fundamental-mode crystal with 7.3 pF load capacitance. |
| 4 | GND | power_in | Pin connection table lists #4 as GND; the datasheet notes the inner side of Pin#1 and Pin#4 is an XTAL blank mounting pad. |
