ECS-2033-080-AU

ECS · Oscillators · SMD2520-4P

ECS-2033-080-AU 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: a VIH of at least 70% VDD or an open pin gives oscillation, and a VIL of at most 30% VDD halts the internal crystal oscillation (no oscillation).
2 Ground power_in Ground connection for the oscillator.
3 Output output Clock output; the datasheet specifies CMOS output with 15 pF maximum load, 10 ns maximum rise and fall times, and 45/55% symmetry at 50% VDD (40/60% for the standard grade).
4 VDD power_in Supply voltage; for the ECS-2033 (+3.3V) it is +3.135 VDC minimum, +3.3 VDC typical and +3.465 VDC maximum.
