# ASDMB-48.000MHZ-LY-T

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

ASDMB-48.000MHZ-LY-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 (VIL < 0.25*Vdd) puts the output in Hi-Z. |
| 2 | GND | power_in | Ground; a ~0.01uF bypass capacitor between pin 2 and pin 4 is recommended. |
| 3 | Output | output | Clock output, 1.0 to 150 MHz, rated for 15, 25 or 40 pF load depending on option. |
| 4 | VDD | power_in | Supply voltage, +1.8V to +3.3V (absolute max 4.0V); bypass with ~0.01uF to pin 2. |
