KDS Daishinku · Temperature Compensated Crystal Oscillators (TCXO) · SMD3225-4P
1XTW26000MAA 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 terminal marked as #1 (index corner) in the pin connection table; the datasheet specifies no separate electrical limit for it. |
| 2 | GND | power_in | Ground terminal listed as GND in the pin connection table; the datasheet specifies no separate electrical limit for it. |
| 3 | Output | output | Clipped sine wave DC-coupled output at the 26.000 MHz nominal frequency, with output level minimum 0.8 Vp-p, measured into 10 kΩ // 10 pF load. |
| 4 | VCC | power_in | Supply input with recommended range 1.7 V to 1.9 V (typical 1.8 V) and absolute maximum rating -0.3 V to +4.6 V; current consumption is max +1.5 mA. |
