Seiko Epson · Temperature Compensated Crystal Oscillators (TCXO) · SMD2016-4P

X1G0041310010 from Seiko Epson, 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 N.C. unconnected Not connected pin; the datasheet says it must not be connected to any other lead, including other N.C. pins.
2 GND power_in Ground reference for the supply (Vcc-GND absolute maximum range -0.3 V to +4.0 V), to be connected to a low-impedance ground.
3 OUT output Clipped sine wave output (Vp-p 0.8 V to 1.5 V into 10 kΩ // 10 pF); a外部 DC-cut capacitor of at least 0.01 µF must be attached externally because it is not included in the TCXO.
4 Vcc power_in Supply voltage input, recommended 2.85 V to 3.15 V (3 V typical); a 0.01 to 0.1 µF by-pass capacitor should be placed as close as possible to this pin and GND.
