Abstract

Circuit arrangement, L[ocal]I[nterconnected]N[etwork] comprising such circuit arrangement as well as method for processing input signals of the LIN In order to further develop a circuit arrangement (100) - for processing at least one input signal (12) from at least one data bus (10) of at least one L[ocal]I[nterconnected]N[etwork] and - for providing the data bus (10) with at least one output signal (18), as well as a corresponding operating method in such way that E[lectro]M[agnetic]E[mission] performance and / or E[lectro]M[agnetic]I[mmunity] performance of the L[ocal]I[nterconnected]N[etwork] (300) is improved, it is proposed to provide - at least one analog-digital converting means (ADC) for converting the analog input signal (12) into at least one digital signal (14) to be processed, and at least one digital-analog converting means (DAC) for converting the processed digital signal (16) into the analog output signal (18).

Description

technical field [0001] The invention relates to a circuit arrangement for: [0002] - processing at least one input signal from at least one data bus of at least one local interconnect network, and [0003] - providing at least one output signal to the data bus. [0004] The invention also relates to a method according to the preamble of claim 8 . Background technique [0005] The Local Interconnect Network (LIN) protocol is a serial communication protocol that efficiently supports the control of mechatronic nodes in distributed automotive applications. This domain is a multiplex bus (so-called Class A multiplex bus) with a single master node and a set of slave nodes. This concept of a single master node and multiple slave nodes is the main feature of the LIN data bus. [0006] Another key feature of the LIN data bus is its low-cost silicon implementation: [0007] - based on common UART / SCI hardware and identical in software, or [0008] - as a pure state machine. ...
