KDS Daishinku · Temperature Compensated Crystal Oscillators (TCXO) · SMD3225-4P

1XTV12800PDA 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, recommended range +0.5 V to +2.5 V (typ. +1.5 V) with positive slope, input resistance at least 500 kΩ.
2 GND power_in Ground connection for the oscillator, serving as the reference for the supply, control voltage and output.
3 Output output Clipped sine wave output (DC-coupled) at 12.8 MHz, minimum output level 0.8 Vp-p, measured into 10 kΩ // 10 pF.
4 VCC power_in Supply voltage input, recommended range +2.85 V to +3.15 V (typ. +3.0 V), absolute maximum −0.3 V to +4.6 V.
