ECS-2520MVLC-049-BN-TR

ECS INTERNATIONAL INC · Global Sourcing Parts · SMD2520-4P

ECS-2520MVLC-049-BN-TR from ECS INTERNATIONAL INC, 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 Standby/output-enable control: ≥0.7Vdd or NC gives active output, ≤0.3Vdd gives high impedance output.
2 Gnd power_in Ground connection.
3 Output output CMOS clock output, rated for 15 pF load with VOL 10% Vdd max and VOH 90% Vdd min.
4 Vdd power_in Supply voltage pin, 1.6 V to 3.6 V.

CAD (KiCad official)

  • Symbol: ECS-2520MVLC-049-BN-TR
  • Footprint: Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm
  • 3D model: SMD2520-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-2520mvlc-049-bn-tr-etched.step / ecs-2520mvlc-049-bn-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-2520mvlc-049-bn-tr.step / ecs-2520mvlc-049-bn-tr.glb are the bare package body.
