# ASE-20.000MHZ-ET

**Abracon LLC** · Pre-ordered Products · SMD3225-4P

ASE-20.000MHZ-ET 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 (STBY) | input | Tri-state standby control: logic "1" (VIH ≥ 0.7*Vdd) or open enables oscillation, while logic "0" (VIL < 0.3*Vdd) stops oscillation with the output in Hi Z. |
| 2 | GND/Case | power_in | Ground and case connection; the datasheet recommends an approximately 0.01uF bypass capacitor between pin 2 and pin 4. |
| 3 | Output | output | CMOS clock output with 15 pF CMOS load, VOH of 0.9*Vdd minimum and VOL of 0.1*Vdd maximum. |
| 4 | Vdd | power_in | Supply voltage from 3.135 V to 3.465 V (3.3 V nominal), with an approximately 0.01uF bypass capacitor recommended between pin 4 and pin 2. |
