# ECS-3225MV-080-BN-TR3

**ECS** · Oscillators · SMD3225-4P

ECS-3225MV-080-BN-TR3 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 | Standby/enable control: output is active when at 0.7*Vdd min or left NC, and high impedance when at 0.3*Vdd max. |
| 2 | Gnd | power_in | Ground connection for the oscillator. |
| 3 | Output | output | CMOS clock output rated for a 15 pF load, with VOL 10% Vdd max and VOH 90% Vdd min. |
| 4 | Vdd | power_in | Supply voltage input, 1.6 V to 3.6 V. |

## CAD (KiCad official)

- Symbol: `ECS-3225MV-080-BN-TR3`
- Footprint: `Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm`
- 3D model: SMD3225-4P (KiCad packages3D, STEP)
- 3D model files: `ecs-3225mv-080-bn-tr3-etched.step` / `ecs-3225mv-080-bn-tr3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ecs-3225mv-080-bn-tr3.step` / `ecs-3225mv-080-bn-tr3.glb` are the bare package body.
