KDS Daishinku · Temperature Compensated Crystal Oscillators (TCXO) · SMD3225-4P
1XZA032768AD19 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 | GND | power_in | Ground connection; the datasheet lists this pin only as GND and gives no electrical limits for it. |
| 2 | Output | output | 32.768 kHz clock output with CMOS levels: VOL max +0.4 V, VOH min Vcc-0.4 V, rise/fall time max 50 ns (Vcc 2.0 to 5.5 V) or 200 ns (Vcc 1.3 to 5.5 V), and load max 15 pF. |
| 3 | VCC | power_in | Supply pin; supply range is +2.0 to +5.5 V in temperature-compensated operation and +1.3 to +5.5 V in timekeeping operation. |
