7L26002007 from TXC Corp, in a SMD2520-4P. 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 or NC | power_in | Pin 1 is connected to GND or left NC per the pin connection table; the test diagram labels AFC (optional voltage control, +7 to +16 ppm at VC = 2.5 V, -16 to -7 ppm at VC = 0.5 V) on the same corner, and OE tri-state control is listed as an option (high ≥ 0.8Vdd enable, low ≤ 0.2Vdd disable, floating = enable). |
| 2 | GND | power_in | Ground connection for the supply and output return. |
| 3 | OUTPUT | output | Clipped sinewave output with minimum 0.8 Vp-p into a 10 kΩ // 10 pF load, with a 1000 pF DC-blocking capacitor (C2) in the test circuit. |
| 4 | VCC | power_in | Supply voltage pin with 1.8 to 3.3 V (±5%) supply range and maximum 2.0 mA supply current; a 10 nF bypass capacitor (C1) should be placed. |
