ECS-TXO-2520-33-120-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 | tri_state | Tri-state pin: the output is active when this pin is high or not connected, and disables the output to Hi-Z when low. |
| 2 | Gnd | power_in | Ground connection for the TCXO. |
| 3 | Output | output | HCMOS clock output with VOL max 10% Vdd and VOH min 90% Vdd, driving a 15 pF load. |
| 4 | Vdd | power_in | Supply voltage Vdd, specified by the part number as +2.5, +2.8 or +3.3 V ±10%. |
