# ASDM1-50.000MHZ-LC-T

**Abracon LLC** · Oscillators · SMD2520-4P

ASDM1-50.000MHZ-LC-T from Abracon LLC, in a SMD2520-4P. 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 | Standby | input | Tri-state standby control: logic 1 (VIH≥0.75*Vdd) or open gives oscillation, logic 0 (VIH<0.25*Vdd) gives Hi-Z output. |
| 2 | GND | power_in | Ground; a ~0.01uF bypass capacitor is recommended between pin 2 and pin 4. |
| 3 | Output | output | Clock output with VOH min 0.8*Vdd and VOL max 0.2*Vdd at 15pF load, Hi-Z when standby is low. |
| 4 | VDD | power_in | Supply voltage, 3.3V ±0.3V for the -1 option (absolute maximum 4.0V); bypass with ~0.01uF to pin 2. |
