KDS Daishinku · Temperature Compensated Crystal Oscillators (TCXO) · SMD3225-4P
1XTV20000CDA from KDS Daishinku, in a SMD3225-4P. 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 +0.5 V to +2.5 V (reference +1.5 V), giving a positive slope of ±9 to ±15 ppm and a minimum input resistance of 500 kΩ. |
| 2 | GND | power_in | Ground connection for the oscillator, referenced for the supply and the DC-cut output. |
| 3 | Output | output | Clipped sine wave output (DC-coupled) at 20.000 MHz, with a minimum output level of 0.8 Vp-p and 40/60 to 60/40 % symmetry at GND level. |
| 4 | VCC | power_in | Supply voltage input, recommended +3.135 V to +3.465 V (typ. +3.3 V), with an absolute maximum rating of -0.3 V to +6.0 V. |
