Demo This demo shows an infotainment and ADAS system based on NXP Ethernet components and is divided in three main parts: Infotainment, Network and ADAS. In the infotainment part, a “Head Unit” ECU plays locally an MPEG movie and also streams it over Ethernet to the second “Rear Seat Unit” ECU. Both ECUs also execute in the backroad the NXP AVB SW stack. This enables the two ECUs to be perfectly synchronized with each other. Therefore the two ECUs can playback the very same video (and audio) frame at the same time on their local displays. In the network part the new Automotive Ethernet Switch (SJA1105EL) and PHYs (TJA1100HN) implement the Ethernet connectivity of the system. The switch executes the AVB “ gPTP ” synchronization SW that enables the infotainment application described above to operate. In the ADAS part a surround view camera captures a video stream and streams it to a “Cluster” ECU also connected via the automotive Ethernet network. The camera is based on the NXP “MPC5604E ” Salsa processor and on a competitor’s BroadR -Reach PHY. This also shows the interoperability of the TJA1100HN PHY with competitor’s products. Features: All displays are implemented with NXP i.MX6 processor, and a full implementation of the NXP Ethernet AVB Stack running on Linux. The camera is based on an NXP Salsa processor ( MPC5304EKIT ) . The Switch board that connects all displays and the camera uses the NXP SJA1105EL Automotive Ethernet switch and the TJA1100HN BroadR-Reach Ethernet PHY ______________________________________________________________________________________________________________ Featured NXP Products: Product Link IEEE 100BASE-T1 compliant Automotive Ethernet PHY Transceiver TJA1100HN | Automotive Ethernet PHY Transceiver | NXP  i.MX 6 Series i.MX 6 Series Applications Processors | Multicore Arm Cortex-A7/A9/M4 | NXP  Audio Video Bridging Software https://www.nxp.com/design/design-services/audio-video-bridging-software:AVB-SOFTWARE?&fsrch=1&sr=4&pageNum=1 Development Kit Enabling Video Over Ethernet with NXP® MPC5604E MCU NXP® MPC5604EKIT:Development Kit | NXP  ___________________________________________________________________________________________________________

  Overview   Vehicle-to-Everything (V2X) technology enables cars to communicate with their surroundings and makes driving safer and more efficient for everyone. By making the invisible visible, V2X warns the driver of road hazards, helping reduce traffic injuries and fatalities. In addition to improving safety, V2X helps to optimize traffic flow, reduce traffic congestion and lessen the environmental impact of transportation. V2X is a key component for full autonomous driving. V2X need message package signing & verification which need high CPU loading if used CPU.

Description Earlier this year NXP organized a promotional opportunity for amateur radio enthusiasts to use their creativity and build their own power amplifier designs. NXP received numerous creative submissions in this competitive Homebrew RF Design Challenge. We appreciate the dedication and enthusiasm from the community that made this contest a success. First place winner An MRF101AN broadband amplifier design with 1 W Input, 100 W Output 1.8-54 MHZ Amplifier deck. (For more information visit:NXP MRF-101 - RFPowerTools )  It is an amplifier with a bandwidth of 1.8MHz to 54MHz. Maximum output power of 100W up to 30MHz and 70W up to 50MHz. Maximum power supply 50V to 4A, with a Voltage Standing Wave Ratio of 1.5:1 maximum. The design dimensions of the PCB is 5x5 cm (2x2 in).  and  310g weight including fan and heat sink. Second place winner A 600W broadband HF amplifier using affordable LDMOS devices (For more information visit: https://qrpblog.com/2019/10/a-600w-broadband-hf-amplifier-using-affordable-ldmos-devices/  ) This project is meant to demonstrate the capabilities of the MRF300 transistors as linear broadband devices in the 2-50MHz range and to be used by radio amateurs as a starting point for a medium-high power amplifier. This is also my entry to the NXP Homebrew RF Design Challenge 2019. To achieve the target of 600W output while also minimizing the level of even-number harmonics, a “push-pull” configuration of two transistors is used. Luckily, the manufacturer made it easy to design the PCB layout for such a thing by offering two versions (the MRF300AN & MRF300BN) that have mirrored pinout. The common TO-247 package is used, with the source connected to the tab. Each individual MRF300 LDMOS transistor is specified at 330W output over a 1.8-250MHz working frequency range, a maximum 28dB of gain and over 70% efficiency. The recommended supply range is 30-50Vdc. By studying the specifications, it looks like with correct broadband matching and some operational safety margin we can get close to 600W output at a voltage of around 45V across a resonably large bandwidth; the aim is to cover 1.8 to 54MHz. Main challenges when designing this amplifier are related to achieving good input and output matching over the entire frequency range as well as maintaining high and flat gain. Good linearity and a low level of harmonic products are mandatory. As the TO-247 is not a package specifically designed for high-power RF, there are some challenges with thermal design and PCB layout as well. Information taken from the essay by the winner. Third place winner A High Efficiency Switchmode RF Amplifier using a MRF101AN LDMOS Device for a CubeSat Plasma Thruster (For more information visit: Research - SuperLab@Stanford ) The Class E amplifier utilizes the active device as a switch, operating in only cutoff (off) and saturated (on) conditions. This minimizes the overlap of voltage and current, reducing losses in the active device. To further reduce loss the Class E amplifier utilizes an inductively tuned resonant network to achieve zero voltage switching, bringing the voltage across the switch to zero before turn on, eliminating energy stored in the output capacitance of the active device that would otherwise be dissipated. This is achieved with an inductively tuned series resonant output filter.  In the Class E amplifier losses are almost entirely determined by the current conducted by the active device so a high drain impedance is desired to maximize efficiency. The drain impedance is ultimately limited by the voltage rating of the switch. For our desired output power of 40W and the maximum voltage rating of 133V for the MRF101AN this impedance is still less than 50 ohms, so a L match circuit is used to match the drain impedance to 50 ohms. The load network in our design provides a drain impedance of 15.4+12.8j. As the MRF101AN will operate in saturation a high drive level is desired. To eliminate the need for a preamplifier and allow for digital control, we use a high speed gate drive chip typically used in switch-mode power supplies, LMG1020, to drive the MRF101AN instead of a RF preamplifier. A resonant network is used to provide voltage gain at the fundamental and third harmonic, providing a quasi-square wave on the gate which helps insure the device remains in saturation. Conclusion It was a close call and highly competitive! Each participant had their own creative, unique and impressive way of displaying the capabilities of these new parts. NXP is always up for new design challenges. Ready for the next challenge?

  Overview   Since 1996 in EU and since 2000 in Europe, the OBD (On-Board Diagnostics) is mandatory for all the cars manufactured. This protocol is used to verify the smoke emissions and check if any car is between the parameters stablished in every country. Also detect engine failures without need to check the engine manually, identifying accurately the problems reducing the repairing time and cost. OBD-II is a sort of computer which monitors emissions, mileage, speed, and other useful data. OBD-II is connected to the check engine light, which illuminates when the system detects a problem. Scan tools can be used to make sense of the diagnostic trouble codes and collect data on other aspects of vehicle’s performance.   Use Cases Hotspot in the CAR Geofences and speed limits Driving habits tracking Insurance and Rental Entertainment   Block Diagram   Products Category Name MCU Product URL 1 MIMXRT1050-EVK: i.MX RT1050 Evaluation Kit Product Description 1 The i.MX RT1050 EVK is a 4-layer through-hole USB-powered PCB.
