**TAITIEN Elec** · Crystal Oscillators · SMD3225-4P

OXETDLJANF-27.0000000MHz from TAITIEN Elec, 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 enable/disable input: enable with high voltage (min 2.31 V at 3.3 V, 1.75 V at 2.5 V, 1.26 V at 1.8 V) or floating, disable with low voltage (max 0.99 V at 3.3 V, 0.75 V at 2.5 V, 0.54 V at 1.8 V) or GND. |
| 2 | GND | power_in | Ground pin; the 0.1 µF by-pass capacitor should be placed as close to the part as possible between the VDD and GND pads. |
| 3 | Output | output | Clock output with 15 pF load; output high min 2.97 V at 3.3 V, 2.25 V at 2.5 V, 1.62 V at 1.8 V, output low max 0.33 V, 0.25 V, 0.18 V respectively, duty cycle 45 to 55 %. |
| 4 | VDD | power_in | Supply voltage pin for 1.8 V, 2.5 V or 3.3 V operation, with supply variation of VDD ±5%; place 0.1 µF by-pass capacitor between VDD and GND pads. |
