WL4456 from WL, in a SOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XOUT | output | Reference output for crystal oscillator with 30 pF load capacitance. |
| 2 | VSS | power_in | Ground connection. |
| 3 | PAOUT | output | Power amplifier output with open-drain topology; external inductor matching network required to achieve output power greater than 10 dBm. |
| 4 | DIN | input | Data input for ASK modulation; DIN=1 enables PLL and PA operation; DIN=0 immediately disables PA and disables PLL after 40 ms delay. |
| 5 | VDD | power_in | Power supply input, 1.8 V to 3.6 V recommended operating range. |
| 6 | XIN | input | Reference input for crystal oscillator: 13.56 MHz at 433 MHz or 9.84375 MHz at 315 MHz. |
