(LIN) transceiver (MTC-30600), together with evaluation boards and software at SAE World Congress 2002. The demonstration shows master and slave LIN functions and verifies device functionality and behavior under simulated real-life conditions. The LIN transceiver chip with Alcatel's new Layer 2 LIN protocol provides optimum performance and safety for today's automotive In-Vehicle-Networking (IVN IVN Interactive Video Network IVN Intravenous IVN Internationale Vereniging voor Neerlandistiek IVN Intravenous Nutrition IVN Integrated Voice Network IVN Intervening Networks IVN in Vehicle Network ) requirements, by delivering guaranteed data transmission at maximum LIN speed. The bullet-proof Layer 2 LIN protocol demonstrates robustness against noise spikes, ground shifts, bus loads and variations in supply voltage level and duty cycle. Today, many solutions do not achieve maximum LIN network speeds without using a crystal oscillator An oscillator that uses a quartz crystal to generate a frequency. Such devices generally output a fixed frequency, but some can be controlled by a tuning voltage over a small range. Contrast with VCO. and additional filtering to cope with harsh automotive conditions. Alcatel's solution is an improved protocol that is able to operate under these conditions. Alcatel's LIN solution is fully compliant with the LIN specification 1.2 standard. As a partner in the LIN consortium, Alcatel supports standardization of the low-cost LIN communication protocol. This certification will mean that LIN products are fully compliant with the LIN Specification -- ensuring real interoperability. About Local Interconnect Network (LIN) The LIN bus is designed to communicate low-rate data from control devices such as door locks, mirrors, car seats and sunroofs at the lowest possible cost. The bus is designed to eliminate as much wiring as possible and is implemented using a single wire in each node. Each node -- e.g., a door panel including door lock, window lift and mirror positioning -- has a slave MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users or state machine that recognizes and translates the instructions specific to that function -- for example, winding a window up or down. The main attraction of the LIN bus is that all the functions are not time-critical, and usually relate to passenger comfort. Typical applications for the LIN bus are assembly units such as doors, seats, climate regulation, lighting, rain sensor A rain sensor or rain switch is a switching device actuated by rainfall. There are two main types of rain sensors. The first is a water conservation device connected to an automatic irrigation system that causes the system to shut down in the event of rainfall. , or alternator alternator: see generator. alternator Source of direct electric current in modern vehicles for ignition, lights, fans, and other uses. The electric power is generated by an alternator mechanically coupled to the engine, with a rotor field coil . For more information on LIN and the Standard, please visit http://www.lin-subbus.org. The presence of semiconductor components in vehicles has increased during recent years. The market for multiplexed automotive electronics, of which the LIN market is relevant, continues to show steady growth. From 2003 onward, it is expected that three to 10 LIN nodes will be installed in new cars. With a worldwide production of 50 million vehicles per year, the LIN market can be regarded as significant. About Alcatel's Automotive Chip Solutions Alcatel is a leading-edge supplier of automotive electronics solutions for car equipment makers worldwide, offering a one-stop-shop service from spec definition to manufacturing. Chips are fabricated in Alcatel's own facilities using the mixed-signal HV (high voltage) semiconductor technology that best supports the application. Automotive ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. and ASSP (Application Specific Standard Part) An ASIC chip that is designed as a generic device for a particular market. Whereas an ASIC is typically used only by its creator, ASSPs are used by many different companies in the design of their products. See ASIC. solutions include chips for powertrain, safety, body, dashboard, IVN, sensor and actuator applications. To date, Alcatel has shipped in excess of 50 million transceivers.
