TKD · Quartz crystal, 40 MHz · SMD 3225, 4 pads
TKD 40 MHz fundamental quartz crystal in a 3.2 x 2.5 mm ceramic SMD package: 12 pF load, +/-10 ppm tolerance. Pads 1 and 3 are the crystal, 2 and 4 the lid ground.
Verification
A person checks each page against its datasheet and signs it off here; the badge turns amber if a checked file changes.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Crystal (datasheet p.1, "Pin Connect": #1 #3 Crystal). |
| 2 | G | passive | Ground (lid). |
| 3 | 3 | passive | Crystal. |
| 4 | G | passive | Ground (lid). |
Note: pads 2 and 4 are both ground (the metal lid). The symbol has one G pin numbered [2,4], KiCad's stacked-pin notation, so wiring that pin connects both pads; the Fusion library connects G to pads "2 4" and the Altium library stacks pins 2 and 4.
