**TKD** · Crystals · SMD3225-4P

SX32Y020000BA1S001 from TKD, 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 | XTAL1 | passive | Crystal terminal connected to one side of the 20.000 MHz, 10 pF load AT-cut crystal (pins 1 and 3 are the crystal pins per the PIN CONNECT table). |
| 2 | GND | power_in | Ground pad per the PIN CONNECT table (pins 2 and 4 are GND). |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the 20.000 MHz, 10 pF load AT-cut crystal (pins 1 and 3 are the crystal pins per the PIN CONNECT table). |
| 4 | GND | power_in | Ground pad per the PIN CONNECT table (pins 2 and 4 are GND). |
