KDS Daishinku · Temperature Compensated Crystal Oscillators (TCXO) · SMD2016-4P
1XXC26000PCA 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 range of +0.5 V to +2.5 V (typ. +1.5 V), positive slope (frequency rises with control voltage), and an input resistance of 500 kΩ min. |
| 2 | GND | power_in | Ground connection for the oscillator; the output symmetry specification (40/60 to 60/40 %) is referenced to the GND level with DC cut. |
| 3 | Output | output | DC-coupled clipped sine wave output with a minimum output level of 0.8 Vp-p into the specified load of 10 kΩ // 10 pF. |
| 4 | VCC | power_in | Supply voltage pin with a recommended range of +2.66 V to +2.94 V (typ. +2.8 V) and an absolute maximum rating of -0.3 V to +4.6 V. |
