**ECS** · Oscillators · SMD2520-4P

ECS-2520MVQ-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 enable input: the output is active when pin 1 is at or above 0.7 x Vdd min or left NC, and high impedance when at or below 0.3 x Vdd max. |
| 2 | Gnd | power_in | Ground reference pin for the oscillator supply. |
| 3 | Output | output | HCMOS clock output with VOL max 0.2 x Vdd and VOH min 0.8 x Vdd, driving a 15 pF CMOS load. |
| 4 | Vdd | power_in | Supply voltage pin; the datasheet specifies a supply range of 1.7 to 3.6 V. |
