**ECS** · Oscillators · SMD3225-4P

ECS-2333-120-BN-TR from ECS, in a SMD3225-4P. 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 at least 70% VDD (or an open pin) enables oscillation, while VIL of at most 30% VDD halts the internal crystal oscillation with a stand-by current of 10 μA. |
| 2 | Ground | power_in | Ground connection for the oscillator. |
| 3 | Output | output | CMOS clock output with VOL at most 10% VDD and VOH at least 90% VDD, 10 ns rise and fall times, specified for a 15 pF CMOS load. |
| 4 | VDD | power_in | Supply voltage input; for the ECS-2333 (+3.3V) series the datasheet specifies 2.97 V min, 3.3 V typ and 3.63 V max. |
