ECS-TXO-2520MV-100-AY-TR

ECS · Temperature Compensated Crystal Oscillators (TCXOs) · SMD2520-4P

ECS-TXO-2520MV-100-AY-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 Output enable: with pin 1 high or not connected the output is active, and pulling it low disables the output to high-impedance (High-Z).
2 Ground power_in Ground connection for the oscillator.
3 Output output CMOS clock output with a logic low at 10% VDD maximum and a logic high at 90% VDD minimum, 45/55% symmetry at 50% VDD, 5 ns rise and fall times, and a 15 pF CMOS load.
4 VDD power_in Supply input, specified from +1.7 to +3.6 VDC (MultiVolt, compatible with 1.8 V, 2.5 V or 3.3 V supplies).
