1XXA26000MAA

KDS Daishinku · Temperature Compensated Crystal Oscillators (TCXO) · SMD2520-4P

1XXA26000MAA from KDS Daishinku, in a SMD2520-4P. 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 +0.4 V to +2.4 V (typ +1.4 V), positive slope, and 100 kΩ minimum input resistance.
2 GND power_in Ground terminal, used as the reference for the supply and output in the measurement circuit.
3 Output output Clipped sine wave output (DC-coupled) with a minimum of 0.8 Vp-p into the 10 kΩ // 10 pF load and harmonics of -8 dBc maximum.
4 VCC power_in Supply voltage of +2.66 V to +2.94 V (typ +2.8 V), with an absolute maximum rating of -0.3 V to +4.6 V.
