1XXB26000MAA

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

1XXB26000MAA 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 GND power_in Ground terminal, marked with the #1 index on the outline; the datasheet's Pin Connections table lists it as GND. The datasheet gives no separate limit for this pin.
2 GND power_in Ground terminal listed as GND in the Pin Connections table; the datasheet gives no separate limit for this pin.
3 Output output Clipped sine wave output (DC-coupled) with a minimum output level of 0.8 VP-P, driving the specified load of 10 kΩ // 10 pF (9 to 11 kΩ and 9 to 11 pF).
4 VCC power_in Supply voltage input; absolute maximum rating is -0.3 to +4.6 V, and recommended operating ranges are +1.71 to +1.89 V, +2.09 to +2.31 V, and +2.66 to +2.94 V.
