Abracon LLC · Crystal Oscillators · SMD3225-4P
ASEK-32.768KHZ-LRT from Abracon LLC, 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 | Logic "1" or open keeps the oscillator running, while logic "0" (VIL < 0.8 Vdc) puts the output in Hi-Z. |
| 2 | GND | power_in | Ground return; the datasheet recommends an approximately 0.01uF bypass capacitor between pin 2 and pin 4. |
| 3 | Output | output | 32.768kHz clock output with 15pF load, VOH = 0.9 * Vdd min and VOL = 0.1 * Vdd max, rise/fall time 40ns typical and 50ns max, symmetry 40/60% max at 1/2 Vdd (option-dependent). |
| 4 | Vdd | power_in | Supply voltage of 3.3 Vdc ±10% standard (options 2.5V ±5% or 1.8V ±5%), with an approximately 0.01uF bypass capacitor recommended to pin 2. |
