2T026000VY from huaxindianzi, 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 | NC or GND | passive | Pin 1 is either not connected or connected to GND; the datasheet marks it with a dot on the package top. |
| 2 | GND | power_in | Ground pin of the 26.000 MHz TCXO. |
| 3 | OUTPUT | output | Clipped sine wave output, at least 0.8 Vp-p (DC-coupled) into a 10kΩ//10pF load, with 40-60% duty ratio. |
| 4 | VDD | power_in | Supply voltage pin, 1.8 to 3.3 V ±5%, with typical supply current of 2.0 mA. |
