KDS Daishinku · Temperature Compensated Crystal Oscillators (TCXO) · SMD2016-4P

1XXD38400MLC from KDS Daishinku, 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 GND power_in Ground terminal (listed as #1 GND in Pin Connections; index mark on pin 1 per the outline drawing), with no further electrical limits stated.
2 GND power_in Ground terminal (listed as #2 GND in Pin Connections), with no further electrical limits stated.
3 Output output Clipped sine wave output (DC-coupled) at 38.4 MHz, with output level of at least 0.8 VP-P into the specified load of 10 kΩ // 10 pF.
4 VCC power_in Supply voltage input; recommended 2.75 V to 2.85 V (2.8 V typical), absolute maximum rating -0.3 V to +4.6 V.
