TROQ · Crystals · SMD2016-4P

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).
