ECS · Temperature Compensated Crystal Oscillators (TCXOs) · SMD2520-4P
ECS-TXO-2520MV-240-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 | Tri-state enable: High or NC keeps the output active, and Low disables the output into high-Z. |
| 2 | Ground | power_in | Ground reference pin for the TCXO. |
| 3 | Output | output | CMOS clock output, with VOL at 10% VDD and VOH at 90% VDD under a 15 pF CMOS load. |
| 4 | VDD | power_in | Supply pin; the datasheet specifies VDD from +1.7 to +3.6 VDC (MultiVolt, 1.8 V, 2.5 V or 3.3 V). |
