chip RC oscillator is provided to the input of a PLL to
generate the system clock. IDT recommends using the
internal oscillator.
The IDTP9030 contains logic to demodulate and decode
error packets sent by the mobile device (Rx-side), and
adjusts power transfer accordingly. The IDTP9030 varies
the switching frequency of the half bridge inverter between
110kHz to 205 kHz. to adjust power transfer. The mobile
device controls the amount of power transferred via a
communication link that exists from the mobile device to
the base station. The mobile device (IDTP9020 or another
WPC-compliant

the following format:

The overall system behavior between the transmitter and
receiver follows the state machine diagram below:
The IDTP9030 performs four phases: Selection, Ping,
Identification & Configuration, and Power Transfer.
