# OT2JI-111-16M

**YXC** · Crystals · SMD3225-4P

OT2JI-111-16M from YXC, 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 | Output enable/tri-state control: output is enabled when high (at least 70% of VDD) or floating, and disabled when low (at most 30% of VDD) or tied to GND. |
| 2 | GND | power_in | Ground connection; a 0.01uF to 0.1uF or larger capacitor is required between VDD and GND. |
| 3 | OUTPUT | output | CMOS clock output rated for a 15pF load, with Voh of at least 90% of VDD and Vol of at most 10% of VDD. |
| 4 | VDD | power_in | Supply voltage input of 1.8V to 3.3V; a 0.01uF to 0.1uF or larger capacitor to GND is required. |
