Abstract

An integrated circuit device has a modulator module that provides a modulation signal comprising one frequency keyed on and off, or alternating between two or more different frequencies or phases that are selected based upon a modulator signal. The one or more frequencies or phases may be selected from a plurality of frequency sources. Switching the one frequency on or off, or between the at least two different frequencies or phases may be synchronized with one or both of the two or more different frequencies or phases so that glitches or spurs are not introduced into the modulation signal. The integrated circuit device may also comprise a processor, memory, digital logic and input-output. Frequency sources may be internal to the digital device or external. The modulator signal may comprise serial data generated from the digital logic and / or processor of the digital device.

Description

[0001] Related Application Cross Reference [0002] This application claims Keith Curtis, Sean Steedman, Jerrold S. Zdenek, and Zeke R. Lundstrum, filed January 26, 2009, entitled "Modulator Module in an Integrated Circuit Device" The priority of commonly-owned US Provisional Patent Application Serial No. 61 / 147,137 is hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to integrated circuit devices, and more particularly, to integrated circuit devices having modulation modules integrated therein. Background technique [0004] Electronic systems such as wireless systems may communicate through some form of electromagnetic signals (eg, radio frequency, infrared, etc.). Furthermore, there are many types of modulation available for electromagnetic signals, eg, amplitude modulation (AM), frequency modulation (FM), phase shift keying (PSK), frequency shift keying (FSK), etc. Current technology only provides an application-s...
