# ECS-3225MVQ-120-CN-TR

**ECS** · Oscillators · SMD3225-4P

ECS-3225MVQ-120-CN-TR from ECS, in a SMD3225-4P. 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 | Output enable: a level at or above 0.7 × Vdd min (or NC) keeps the output active, while a level at or below 0.3 × Vdd max puts the output in high impedance. |
| 2 | Gnd | power_in | Ground reference for the oscillator supply. |
| 3 | Output | output | HCMOS clock output driving a 15 pF load, with VOL max 0.2 × Vdd and VOH min 0.8 × Vdd. |
| 4 | Vdd | power_in | Supply voltage input, specified from 1.7 V to 3.6 V (MultiVolt). |
