ECS-2018-240-BN 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 control: VIH of 70% VDD min enables oscillation, VIL of 30% VDD max halts the internal crystal oscillation, and an open pad also gives oscillation. |
| 2 | Ground | power_in | Ground connection for the oscillator. |
| 3 | Output | output | CMOS clock output with a 15 pF maximum load, VOL at 10% VDD maximum, VOH at 90% VDD minimum, and 10 ns maximum rise and fall times between 10% and 90% levels. |
| 4 | VDD | power_in | Supply voltage input, specified at 1.71 V min, 1.80 V typical, and 1.89 V max. |
