1XXC26000PKA

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

1XXC26000PKA 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 VCONT input Frequency control voltage input with a control range of +0.3 V to +1.5 V (reference +0.9 V) and a positive slope, where frequency rises with control voltage; input resistance is at least 500 kΩ.
2 GND power_in Ground terminal for the oscillator, used as the reference for the supply and the clipped sine wave output.
3 Output output Clipped sine wave output (DC-coupled) with a minimum output level of 0.8 VP-P, specified with load 10 kΩ // 10 pF.
4 VCC power_in Supply voltage input, recommended 1.7 V to 1.9 V (typical 1.8 V), with an absolute maximum rating of -0.3 V to +4.6 V.
