ISO 17987-4-2016 pdf free.Road vehicles一Local Interconnect Network (LIN])一Part 4: Electrical physical layer (EPL] specification 12 V/24 V. ISO 17987 (all parts) and ISO 14229-7 are based on the conventions specified in the OSl Service Conventions (see ISO/IEC 10731) as they apply for physical layer, protocol, network and transport protocol and diagnostic services. 5 Electrical physical layer requirements 5.1 Bit rate deviation The bit rate deviation of the LIN medium describes the bit rate deviation from a referenced bit rate. It is the sum of the following parameters: — inaccuracy of setting the bit rate (systematic failure due to granularity of the configurable bit rate); — clock deviation over temperature and supply voltage range; — clock source stability of the slave node starting from the end of the sync byte field up to the end of the entire LIN frame (last sampled bit) when performing synchronization; — bit time measurement failure of the slave node; — clock source stability of the master node starting from the end of the sync byte field up to the end of the entire UN frame (last transmitted bit). On-chip clock may achieve a frequency deviation of better than ±14 % with internal calibration. This bit…

ISO 13400-3:2016 pdf free download.Road vehicles Diagnostic communication over Internet Protocol (DoIP) Part 3:Wired vehicle interface based on IEEE 802.3 Véhicules routiers — communication de diagnostic au travers dii protocole internet (DoIP) — Partie 3: lnterftice dii véhicule câblé stir Ia base de I’IEEE8O2.3. 7 Ethernet physical and data link layer requirements 7.1 General information Ethernet is a collection of several standards for different tranSmiSSion technologies and speeds contained in IEEE 802.3 and is a frame-based networking technology for wired local area networks. Frames are defined as the foi’mat of data iackets on the wire. The Internet Protocol (lPv4) theoretically allows for a maximum IP packet length of 64 Khytes. This size is limited by the Ethernet specification, which defines a 16-bit-length field and requires a minimum packet length of64 bytes, as well as allowing for a maximum payload length of 1 500 bytes. Consequently, IP packets can have a maximum length of only 1 500 bytes on Ethernet. Howevei IP allows for fragmentation of IP packets over multiple Ethernet frames to work around this limitation. The rules for fragmentation of IP packets differ between IPv6 and lPv4 and are not specified in this document. The Ethernet connection of a…
