# ECS-2520MVLC-018-BN-TR

**ECS** · Oscillators · SMD2520-4P

ECS-2520MVLC-018-BN-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 | Standby/tri-state control: the output is active when this pin is at least 0.7 × Vdd or left not connected, and goes to high impedance when it is at most 0.3 × Vdd. |
| 2 | Gnd | power_in | Ground pin for the oscillator supply. |
| 3 | Output | output | CMOS clock output with VOL at most 10% Vdd and VOH at least 90% Vdd, specified for a 15 pF CMOS load. |
| 4 | Vdd | power_in | Supply voltage pin; the datasheet specifies a supply range of 1.6 V to 3.6 V. |
