ECS-TXO-2520MV-400-AN-TR from ECS, 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 | Tri-State | input | Tri-state control: high or NC makes the output active, low disables the output to High-Z. |
| 2 | Ground | power_in | Ground connection. |
| 3 | Output | output | CMOS clock output, up to 15 pF load, high-Z when pin 1 is low. |
| 4 | VDD | power_in | Supply voltage input, 1.7 to 3.6 VDC. |
