# L32AOC012288PBL

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

L32AOC012288PBL from Lucki, 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 | E/D | input | Enable/disable input: high or open enables output at pin 3, low (VIL 0 to 0.3*VDD) puts pin 3 in high impedance and stops oscillation, and a low-plus-floating state is unstable and disallowed. |
| 2 | GND | power_in | Ground reference; a 0.01uF bypass capacitor should be placed between VDD (pin 4) and GND (pin 2) to minimize power supply line noise. |
| 3 | Output | output | HCMOS clock output at 12.288MHz that is active when pin 1 is high or open and high impedance when pin 1 is low, with the datasheet advising a load of 15pF (drive one CMOS/TTL gate) and a 4.0 ns maximum rise and fall time. |
| 4 | VDD | power_in | Supply voltage of 3.3V ±10%, bypassed to GND (pin 2) with a 0.01uF capacitor. |
