# ECS-2333-250-BN-TR

**ECS** · Crystal Oscillators · SMD3225-4P

ECS-2333-250-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: VIL at 30% VDD max halts internal crystal oscillation (no oscillation), while VIH at 70% VDD min or an open pin allows oscillation. |
| 2 | Ground | power_in | Ground connection for the oscillator. |
| 3 | Output | output | Clock output; CMOS output with 10% VDD low level (VOL) and 90% VDD high level (VOH), driving a 15 pF maximum CMOS load. |
| 4 | VDD | power_in | Supply voltage input; the ECS-2333 (+3.3V) is specified at 2.97 V min, 3.3 V typ, and 3.63 V max. |
