ECS-2520MV-250-CN-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: the output is active when this pin is at 0.7 x Vdd min or left NC, and goes high impedance when it is at 0.3 x Vdd max. |
| 2 | Gnd | power_in | Ground connection for the oscillator. |
| 3 | Output | output | CMOS clock output with VOL at most 10% Vdd and VOH at least 90% Vdd, specified for a 15 pF load. |
| 4 | Vdd | power_in | Supply voltage pin; the ECS-2520MV operates from 1.6 V to 3.6 V. |
