ECS-2520S25-250-FN-TR
ECS · Crystal Oscillators · SMD2520-4P
ECS-2520S25-250-FN-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: the output is active when pin 1 is High or left NC, and goes to high impedance when pin 1 is Low. |
| 2 | Gnd | power_in | Ground pad for the oscillator supply return. |
| 3 | Output | output | HCMOS clock output with 15 pF load; VOL is 10% Vdd max and VOH is 90% Vdd min, with 5 ns max rise and fall time (10%-90% Vdd). |
| 4 | Vdd | power_in | Supply pin; the datasheet specifies Vdd ±10% of +1.8, +2.5, +3.0 or +3.3 V DC depending on the part-number voltage code. |
