PT4455 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 pin, connected to the crystal network (X1 with C1/C2) in the application circuit. |
| 2 | VSS | power_in | Ground connection for the device. |
| 3 | PAOUT | output | Power amplifier output pin that drives the RF output stage. |
| 4 | DIN | input | Data input pin for OOK/ASK modulation of the transmitter. |
| 5 | VDD | power_in | Power supply pin; the datasheet specifies an operating range of 2.2 V to 3.6 V. |
| 6 | XIN | input | Oscillator input pin, connected to the crystal network in the application circuit; a parallel resistor R5 (560K) can be populated across XIN to help oscillation with high crystal ESR. |
