RX38400005 from TROQ, in a SMD2016-4P. 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 (#1,#3 are the X'TAL connections) of the 38.400000 MHz fundamental-mode unit with CL 8 pF. |
| 2 | GND | power_in | Connected to the thermistor return, ground and the metal lid. |
| 3 | XTAL2 | passive | Crystal terminal (#1,#3 are the X'TAL connections) of the 38.400000 MHz fundamental-mode unit with CL 8 pF. |
| 4 | THERM | passive | Thermistor terminal of the 100K±1% (25℃), B=4250±1% K thermistor, the other side of which is tied to pin 2 (GND). |
