INTEGRATED CIRCUIT HAVING FREQUENCY DEPENDENT NOISE AVOIDANCE
First Claim
Patent Images
1. An apparatus, comprising:
- a clock source that generates a first clock signal for clocking a first clocked module, the first clock signal having a rate such that frequency dependent noise components associated with the first clock signal are outside a given frequency range that causes adverse performance in the first clocked module; and
a rate adapting module that produces an operation dependent clock signal from the first clock signal for clocking a second clocked module that is rate dependent.

Abstract
A clock source generates a first clock signal for clocking a first clocked module and a rate adapting module produces an operation dependent clock signal from the first clock signal for clocking a second clocked module that is rate dependent. The first clock signal has a rate such that frequency dependent noise components associated with the first clock signal are outside a given frequency range that causes adverse performance in the first clocked module.

11. A radio frequency device, comprising:
-
a clock module that generates a first clock signal having a rate such that frequency dependent noise components associated with the first clock signal are outside a given frequency range, the clock module further producing an operation dependent clock signal from the first clock signal; a low noise amplifier that is susceptible to adverse performance when the frequency dependent noise components are within the given frequency range, wherein the low noise amplifier is clocked based on the first clock signal; and a baseband processing module having at least one function that is rate dependent and clocked based on the operation dependent clock signal. - View Dependent Claims (12, 13, 14, 15, 16, 17)
