ECS-2018-120-BN

ECS · Pre-ordered Products · SMD2520-4P

ECS-2018-120-BN 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 control: VIH at 70% VDD minimum or an open pin gives oscillation, while VIL at 30% VDD maximum halts the internal crystal oscillation (Pin #1 = VIL, no oscillation).
2 Ground power_in Ground reference pin for the oscillator.
3 Output output Clock output into a CMOS load of 15 pF, with 45/55 % symmetry at 50% VDD, 10 ns rise and fall times, VOL at 10% VDD and VOH at 90% VDD.
4 VDD power_in Supply input rated 1.71 V to 1.89 V (typ. 1.80 V).

CAD (KiCad official)

  • Symbol: ECS-2018-120-BN
  • Footprint: Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm
  • 3D model: SMD2520-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-2018-120-bn-etched.step / ecs-2018-120-bn-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-2018-120-bn.step / ecs-2018-120-bn.glb are the bare package body.

Provenance

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