ECS-TXO-2520MV-240-AN-TR

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

ECS-TXO-2520MV-240-AN-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: pin high or open (NC) keeps the output active, while pin low disables the output into high-impedance (High-Z).
2 Ground power_in Ground reference for the oscillator.
3 Output output CMOS clock output with VOL of 10% VDD and VOH of 90% VDD, specified for a 15 pF CMOS load.
4 VDD power_in Supply pin; MultiVolt input with a range of +1.7 to +3.6 VDC.
