Problems solved by technology

[0003] However, since the clock signal of the receiver needs to constantly adjust the phase to track the clock signal of the transmitter, therefore, in the case of unstable phase, the calculated value of some circuits may need to be re-converged. resulting in lower overall system performance

Embodiment Construction

[0018] Certain terms are used in the specification and claims above to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and the above-mentioned scope of patent application do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The "comprising" mentioned in the entire specification and the above-mentioned claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection ...

Abstract

The invention provides a network signal processing device, which comprises a first signal processing module, a first sampling frequency converter, a second signal processing module, a second sampling frequency converter, and a time sequence controller, wherein the first signal processing module is used for processing a network signal to output a first processing signal; the first sampling frequency converter is used for performing signal frequency conversion on the first processing signal according to a first time sequence adjusting signal and outputting a first conversion signal; the second signal processing module is used for processing the first conversion signal to output a second processing signal; the second sampling frequency converter is used for performing signal frequency conversion on the second processing signal according to a second time sequence adjusting signal and outputting a second conversion signal; and the time sequence controller is used for generating the first and second time sequence adjusting signals.

Description

technical field [0001] The present invention relates to a network signal processing device, especially a device with a first sampling frequency converter, a second sampling frequency converter and a timing controller, and the first and second sampling frequency converters are respectively based on the timing controller The generated first and second timing adjustment signals are used to convert the signal frequency of the signals in the asynchronous domain and the synchronous domain, so that the signals in the asynchronous domain and the synchronous domain respectively have the same operating frequency of the network signal processing device. Background technique [0002] Generally speaking, when the transmitter (TX) of the communication system transmits the signal and the receiver (RX) receives the signal, the transmitter and the receiver will transmit the signal in a synchronous manner, but in practice , to synchronize the transmitter and the receiver, a clock generator ne...
