Patent ID: 6912260

Claim:
A wireless receiver which receives digital data from a remote transmitter via a radiofrequency communications link comprised of a plurality of data frames, which wireless receiver is comprised of: a counter with a count input that is derived from a system clock signal generated within the wireless receiver, the counter also including a latch input that is derived from a frame synchronization signal generated during each data frame; a loop filter with an input derived from the counter output; a loop gain block, which gain block receives an input derived from the loop filter output; a frequency-tuneable oscillator which receives the output of the loop gain block and generates the system clock signal, the frequency of the system clock signal being dependent upon the loop gain block output; wherein the loop gain block output is proportional to a difference between the output of the loop filter and a configurable calibration value, whereby the frequency of the system clock signal is synchronized with the remote transmitter.
