ECS-327KE-TR

ECS · Pre-ordered Products · SMD3225-4P

ECS-327KE-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 Tri-state control: a voltage at or above 90% VDD (min) keeps oscillation running, while a voltage at or below 10% VDD (max) halts the internal crystal oscillation and puts the output in high impedance.
2 GROUND power_in Ground reference pin for the oscillator.
3 OUTPUT output CMOS clock output with a stated load of 15 pF, VOL maximum +0.4 VDC and VOH minimum VDD-0.4 V at +25°C.
4 VDD power_in Supply pin; the absolute supply voltage range is +1.425 to +5.5 VDC.

CAD (KiCad official)

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

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
