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. |
