**Kyocera AVX** · Crystals · SMD3225-4P

CX3225SB19200D0FPLCC from Kyocera AVX, 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 | HOT | passive | Pad 1 is a HOT crystal terminal, identified as pin 1 by the [K] mark on the package, and the datasheet states no further electrical limits for it. |
| 2 | GND | power_in | Pad 2 is a GND pad in the pin layout, and the datasheet states no electrical limits for it. |
| 3 | HOT | passive | Pad 3 is the second HOT crystal terminal, diagonally opposite pad 1 in the pin layout, and the datasheet states no further electrical limits for it. |
| 4 | GND | power_in | Pad 4 is a GND pad in the pin layout, and the datasheet states no electrical limits for it. |
