ECS-TXO-2520MV-250-AN-TR

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

ECS-TXO-2520MV-250-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: when high or not connected the output is active, and when low the output is disabled and goes to High-Z.
2 Ground power_in Ground connection for the TCXO.
3 Output output CMOS clock output, with VOL at most 10% Vdd and VOH at least 90% Vdd, 45/55 % symmetry at 50% VDD, and 15 pF output load.
4 VDD power_in Supply input, specified from +1.7 V to +3.6 V (MultiVolt, 1.8 V, 2.5 V or 3.3 V nominal).
