ECS-TXO-2520-33-200-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 enable: output is active when high or not connected and is disabled to Hi-Z when low. |
| 2 | GND | power_in | Ground reference pin for the TCXO. |
| 3 | Output | output | HCMOS clock output with VOL at most 10% Vdd and VOH at least 90% Vdd, driving 15 pF load. |
| 4 | Vdd | power_in | Supply voltage pin; the part number specifies +2.5, +2.8 or +3.3 V DC, each ±10%. |
