TST · Crystals · SMD3225-4P
TZ3451D 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 connected to one side of the resonator, for the 40.000MHz fundamental oscillator circuit with 10 pF load capacitance. |
| 2 | GND | power_in | Ground pad, connected to the package lid/ground per the pin connection table. |
| 3 | IN/OUT | passive | Crystal terminal connected to the other side of the resonator, for the 40.000MHz fundamental oscillator circuit with 10 pF load capacitance. |
| 4 | GND | power_in | Ground pad, connected to the package lid/ground per the pin connection table. |
