**ECS** · Oscillators · SMD2016-4P

ECS-2016MV-250-CN-TR3 from ECS, in a SMD2016-4P. 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 | tri_state | Tri-state enable: output is active when pin 1 is at 0.7 * Vdd min or left NC, and goes high impedance when at 0.3 * Vdd max. |
| 2 | Gnd | power_in | Ground reference pin for the oscillator supply. |
| 3 | Output | output | HCMOS clock output with 15 pF CMOS load, VOL 10% Vdd max and VOH 90% Vdd min. |
| 4 | Vdd | power_in | Supply voltage input, specified from 1.6 V to 3.6 V (MultiVolt, compatible with 1.8 V, 2.5 V or 3.3 V supplies). |
