PT4456 from PTC Princeton Tech, in a SOT-23-6. 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 | XOUT | output | Oscillator output, the crystal driver pin of the on-chip oscillator (pin function as stated in the pin description table; no electrical limits are given for this pin). |
| 2 | VSS | power_in | Ground connection for the device. |
| 3 | PAOUT | output | Power amplifier output of the FSK transmitter. |
| 4 | DIN | input | Data input for the FSK modulation. |
| 5 | VDD | power_in | Power supply; the features list gives a 2.2 V to 3.6 V operation range. |
| 6 | XIN | input | Oscillator input of the on-chip oscillator, which connects to the crystal resonator. |
