CLOCK SYNCHRONIZATION IN AN RFID EQUIPPED DEVICE

摘要

Embodiments of a method for clock synchronization in a radio frequency identification (RFID) equipped device, an RFID equipped device, and a hand-held communications device are described. In one embodiment, a method for clock synchronization in an RFID equipped device involves measuring a difference between a field clock frequency generated from an external clock and an internal clock frequency generated from an internal clock and generating outgoing bits in the RFID equipped device in response to the measured difference. Generating the outgoing bits involves adjusting the bit length of at least one of the outgoing bits in response to the measured difference. Other embodiments are also described.
