ECS-2520S33-400-FN-TR

ECS · Pre-ordered Products · SMD2520-4P

ECS-2520S33-400-FN-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: the output is active when this pin is high or NC, and goes to high impedance when it is low.
2 Gnd power_in Ground pad for the oscillator supply return.
3 Output output HCMOS clock output with VOL at most 10% of Vdd and VOH at least 90% of Vdd, specified for a 15 pF load.
4 Vdd power_in Supply pin, +3.3 V DC nominal for this variant with ±10% tolerance.

CAD (KiCad official)

  • Symbol: ECS-2520S33-400-FN-TR
  • Footprint: Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm
  • 3D model: SMD2520-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-2520s33-400-fn-tr-etched.step / ecs-2520s33-400-fn-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-2520s33-400-fn-tr.step / ecs-2520s33-400-fn-tr.glb are the bare package body.
