摘要:
A handheld audio system having a radio signal decoder that includes a method for adjusting a system clock. Adjusting the system clock includes receiving a signal at a rate of a receive clock, wherein the signal includes data at a transmit rate. An error term is determined between the receive rate and the transmit rate. Based on the receive clock and the error term, where the error term is non-zero, a clock signal is generated.

A digital clock generator includes a base clock generator for generating a base clock signal at a variable base clock frequency in response to a control signal. A digital clock controller generates a digital clock signal having a substantially constant number of digital clock cycles over a predetermined period.

A sample rate converter includes an up-conversion module, a linear interpolator module, and a parameter control module. The up-conversion module is operable to convert a first data rate to a second data rate of a data signal. The linear interpolator module is operable to receive the data signal at the second data rate and to produce therefrom a data signal at a desired rate based on at least one parameter. The parameter control module is operable to produce the at least one parameter based on the desired rate.

A system on a chip integrated circuit includes an analog front end for receiving a received radio signal having a plurality of channel signals, each of the plurality of channel signals being modulated at one of a corresponding plurality of carrier frequencies, and for converting a selected one of the plurality of channel signals into a digital signal. A digital clock generator generates a digital clock signal at a digital clock frequency that varies based on the selected one of the plurality of channel signals. The digital clock frequency, and integer multiples of the digital clock frequency, are not substantially equal to the carrier frequency of the selected one of the plurality of channel signals. A digital section converts the digital signal into at least one audio signal that corresponds to the selected one of the plurality of channels, based on the digital clock signal.
摘要:
A method for managing power of a battery-powered handheld audio device by receiving an indicia of signal quality for a received continuous-time radio signal. The method compares the indicia of signal quality to a signal quality threshold. Upon a favorable comparison, enacting a first analog signal conditioning setting. Upon an unfavorable comparison, enacting a second analog signal conditioning setting. The method further provides, upon the favorable comparison, disabling a digital filtering operation, and upon the unfavorable comparison, enabling the digital filtering operation.
摘要:
A method of manufacturing a high frequency integrated circuit begins by positioning a die within a package, wherein the die includes a circuit that processes a high frequency signal and at least one bond pad operably coupled to the circuit, and wherein the package includes a plurality of bond posts, wherein at least one of the plurality of bond posts is allocated to the at least one bond pad. The method continues by bonding a first plate of a capacitor to the at least one bond pad. The method continues by bonding a second plate of the capacitor to the at one of the plurality of bond posts.
