# ASE-50.000MHZ-LC-T

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

ASE-50.000MHZ-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 | STBY | input | Tri-state/standby control: logic 1 (VIH≥0.7*Vdd) or open gives oscillation, logic 0 (VIL<0.3*Vdd) gives no oscillation/Hi-Z output with 10 µA max standby current. |
| 2 | GND/Case | power_in | Ground and case connection; a ~0.01uF bypass capacitor is recommended between pin 2 and pin 4. |
| 3 | Output | output | CMOS clock output with 15 pF rated load, VOH 0.9*Vdd min and VOL 0.1*Vdd max, going Hi-Z when standby is active. |
| 4 | Vdd | power_in | Supply voltage 3.135 V to 3.465 V (3.3 V typical); place a ~0.01uF bypass capacitor between pin 4 and pin 2. |
