Communication Device and Method of Determining a Ranging Value in the Communication Device

摘要

A communication device and a method of determining a ranging value in the communication device are provided. The communication device, includes: a transmitter path, including: a transmitter clock generating circuit configured to generate a transmitter clock signal; a receiver path, including: a clock recovery circuit configured to recover a receiver clock signal from a received signal; a comparator circuit coupled to the clock recovery circuit and configured to compare the receiver clock signal and the transmitter clock signal to generate an output signal; a ranging determination circuit configured to determine a ranging value based on the output signal.
