1XTV21700PAA 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 (typ +1.5 V), positive slope, and a minimum input resistance of 500 kΩ. |
| 2 | GND | power_in | Ground connection, which is the reference for the output symmetry specification (40/60 % to 60/40 %, DC cut). |
| 3 | Output | output | DC-coupled clipped sine wave output with a minimum output level of 0.8 Vp-p at the specified load of 10 kΩ // 10 pF. |
| 4 | VCC | power_in | Supply voltage input of +2.85 V to +3.15 V (typ +3.0 V), with an absolute maximum rating of -0.3 V to +4.6 V. |
