ECS-327ATQMV-AS-TR

ECS · Crystal Oscillators · SMD3225-4P

ECS-327ATQMV-AS-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 or NC input Output enable: a level at or above 0.7 x Vdd (min) or no connection keeps the output active, while a level at or below 0.3 x Vdd (max) puts the output in high impedance.
2 Gnd power_in Ground reference pin for the oscillator.
3 Output output HCMOS clock output with VOL at most 10% Vdd and VOH at least 90% Vdd, specified for a 15 pF CMOS load.
4 Vdd power_in Supply voltage pin, specified from 1.62 V to 3.63 V.

CAD (KiCad official)

  • Symbol: ECS-327ATQMV-AS-TR
  • Footprint: Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm
  • 3D model: SMD3225-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-327atqmv-as-tr-etched.step / ecs-327atqmv-as-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-327atqmv-as-tr.step / ecs-327atqmv-as-tr.glb are the bare package body.
