Embodiment Construction

[0010] The following disclosure provides various embodiments, or examples, for implementing features of the presented subject matter. Specific examples of components and arrangements are described below to simplify the present disclosure. Of course, these are examples only and are not limiting. For example, in the description below, forming a first feature over or on a second feature can include embodiments where the first and second features are formed in direct contact, and can also include embodiments where the first and second features can be formed in direct contact. An embodiment in which an additional feature is formed between two features such that the first feature and the second feature may not be in direct contact. Additionally, the present disclosure may repeat reference numbers and / or letters in various instances. This repetition is for simplicity and clarity and does not in itself determine the relationship between the various embodiments and / or configurations ...

Abstract

A carrier generator includes a phase accumulator configured to receive a frequency command word (FCW) signal. The carrier generator includes an adder connected to the phase accumulator; and a loop filter configured to receive an output of the adder. The carrier generator includes a plurality of tuning arrangements, each tuning arrangement is configured to receive an output of the loop filter. Each tuning arrangement includes an electronic oscillator configured to receive the output of the loop filter. Each tuning arrangement includes a voltage controlled delay line (VCDL) configured to receive an output of the electronic oscillator, and to provide a tuning arrangement output. Each tuning arrangement includes a phase detector configured to receive a corresponding recovered clock signal and a feedback from a corresponding tuning arrangement output. Each tuning arrangement includes a counter configured to receive an output of the phase detector and to provide an output to the VCDL.

Description

technical field [0001] Embodiments of the present invention relate to the field of integrated circuits, and more specifically, to a carrier generator. Background technique [0002] In a packaged integrated circuit, there are many individual devices such as memory, analog-to-digital converters, wireless communication devices, application processors, and so on. The individual devices communicate via a bus such as a Serial Peripheral Interface (SPI) or an Inter-Integrated Circuit (I 2 C)) communication. As the bandwidth requirements of individual devices increase, the bus limits the amount of data transfer between the devices. A Radio Frequency Interconnect (RFI) has been implemented that links the devices to perform communication between the devices. Contents of the invention [0003] An embodiment of the present invention provides a carrier generator including: a phase accumulator, an adder, a loop filter, and multiple tuning arrangements. The phase accumulator is confi...
