**Hosonic Elec** · Oscillators · SMD3225-4P

D3SX38E0X0003E from Hosonic Elec, 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 | E/D | input | Enable/disable input: H or open (VIH≥0.7VDD) enables output at pin 3, L (VIL≤0.3VDD) puts pin 3 in high impedance. |
| 2 | GND | power_in | Ground; place a 0.01uF bypass capacitor between VDD (pin 4) and GND (pin 2). |
| 3 | Output | output | HCMOS clock output of 38.400000MHz, rated for 15pF load, high impedance when pin 1 is low. |
| 4 | VDD | power_in | Power supply of 3.3V±10%, decoupled with a 0.01uF bypass capacitor to GND. |
