**YXC Crystal Oscillators** · Crystal Oscillators · SMD2520-4P

O93EL89CEI-112YLC-25M from YXC Crystal Oscillators, 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 | OE/ST/NC | input | Output enable, standby or no-connect pin: H gives specified frequency output, L makes the output low (stop in OE mode, sleep mode in standby with supply current reduced to 400uA); if tied to VDD or left open the specified frequency is output, and in NC version the pin has no function. |
| 2 | GND | power_in | Electrical ground. |
| 3 | OUT | output | Oscillator output (CMOS, 15pF load). |
| 4 | VDD | power_in | Power supply voltage (1.8 V, 2.5 V or 3.3 V versions, ±10% tolerance). |
