# ASEKDV-32.768KHZ-LC-T

**Abracon LLC** · Crystal Oscillators · SMD3225-4P

ASEKDV-32.768KHZ-LC-T 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 | INH | input | Active-low inhibit/tri-state control: open or high (VIH≥0.7*Vdd) enables output oscillation, low (VIL<0.3*Vdd) gives High-Z with no oscillation; must not float and must be tied to Vdd if unused. |
| 2 | GND | power_in | Ground; a bypass capacitor of approximately 0.01µF is recommended between pin 2 and pin 4. |
| 3 | Output | output | 32.768kHz CMOS/LVCMOS clock output rated for a 15 pF load, with VOH 0.9*Vdd and VOL 0.1*Vdd, High-Z when INH is low. |
| 4 | Vdd | power_in | Supply voltage pin for continuous operation from 1.62 V to 3.63 V, with approximately 0.01µF bypass capacitor recommended to GND. |
