7M19200005 from TXC Corp, 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 | XTAL1 | passive | Crystal terminal (pin 1, marked by the pin 1 location dot) of the 19.200000 MHz fundamental-mode crystal with 7 pF load capacitance and 100 uW maximum drive level, shown unlabelled in the internal view connection. |
| 2 | GND | power_in | Ground pad connected to the package lid, labelled GND in the internal view connection of the 3.2x2.5 mm package. |
| 3 | XTAL2 | passive | Second crystal terminal of the 19.200000 MHz fundamental-mode crystal with 7 pF load capacitance and 50 ohm maximum effective resistance, shown unlabelled in the internal view connection. |
| 4 | GND | power_in | Ground pad connected to the package lid, labelled GND in the internal view connection of the 3.2x2.5 mm package. |
