1XXA26000MCA

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

1XXA26000MCA 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, range +0.3 to +1.5 V (+0.9 V typ.) with positive slope and input resistance of 500 kΩ min.
2 GND power_in Ground connection.
3 Output output Clipped sine wave output (DC-coupled), 0.8 Vp-p min. into 10 kΩ // 10 pF load.
4 VCC power_in Supply voltage pin, recommended +1.7 to +2.94 V (+1.8 V typ.), absolute maximum -0.3 to +4.6 V.
