PT4456

PTC Princeton Tech · RF Transceiver ICs · SOT-23-6

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.

CAD (KiCad official)

  • Symbol: PT4456
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: pt4456-etched.step / pt4456-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pt4456.step / pt4456.glb are the bare package body.
