Automotive infotainment guide
Design considerations
With the race to deliver the best features in new cars escalating, the infotainment system is now a key focus in the automotive design process. To support the growing importance of infotainment, Texas Instruments offers a strong portfolio and design support. TI's broad analog and digital embedded and applications processing portfolio provides improved audio quality and system speed, efficient power management and low power consumption for applications such as car audio, navigation systems, power supply, as well as in-car and personal entertainment.
Infotainment systems combine entertainment, multi-media and driver information functions in one module. They offer AM/FM or satellite radio, DC/DVD player for music and video, navigation system, data and multimedia ports (USB, Bluetooth®, line in, line out, video in) as well as general and vehicle status information.
Audio input/output
The audio input front end and audio output is often combined into a single codec. The audio line level input from the source is converted into digital samples by the ADC and feed to the system's DSP. On the output side, ADCs convert the digital output to an analog signal, which is amplified to the levels needed by the speakers or headphones used with the system. By using Class-D amplifiers the system's power efficiency can exceed 90% while maintaining low THD. This improved efficiency leads to significant size, weight and heat reductions. TI's Class-D car audio solutions exhibit extremely low EMI levels and are being used in OEM systems with stringent EMC requirements.
The audio DSP performs I/Q demodulation and outputs digital audio and data. This includes functions like: · Volume, treble, bass and sound
effects · Mixing input channels and digitally
processing multiple channels · Performing sound effects processing
such as Dolby® Pro Logic® II, SRS® Circle SurroundTM II, TruSound and other audio algorithms · The uC + DSP controls the user interface, bus interface and network interface as well as GPS navigation and touch screen control · It is also used to process and output video data from multiple sources
Power management
The power supply is connected to the 12 V or 24 V board net and regulates down/up to voltages for DSP, uC, memory and ICs and functions in the infotainment system. In some cases there may be 10 or more different power rails, making the design of the power supply a critical task when trying to design for size, cost and efficiency.
Linear regulators with low quiescent current help reduce battery leakage current during standby operating modes (ignition off), are load dump voltage tolerant for direct battery devices and need low drop-out and tracking for low battery crank operation.
Beyond providing increased conversion efficiencies, switching power supplies provide: · EMI improvement with slew rate
control of the switching FET · Frequency hopping · Spread spectrum or triangulation
method for attenuation of peak spectral energy · Low Iq · Soft start for power sequencing and in rush current limitation · Phased switching for multiple SMPS's regulators to minimize input ripple current and lower input capacitance · Higher switching frequency for smaller components (L and C's) · SVS functions for brown out indications.

Design considerations
Bi-directional FPD-link III
Communication interfaces allow data exchange between independent electronic modules in the car, the remote sub modules of the infotainment system as well as external devices like USB memory or video sources.
Bi-directional FPD-Link III embedded clock Ser/Des with ultra-low EMI signaling integrate data, clock, and real-time control over a single twisted wire pair.
High-speed CAN
High speed CAN (up to 1 Mbps, ISO 119898) is a two wire, fault tolerant differential bus. With a wide input common mode range and differential signal technology it serves as the main vehicle bus for connecting the various electronic modules in the car with each other. LIN supports low speed (up to 20 kbps) single bus wire networks, primarily used to communicate with remote sub functions of the infotainment system. LVDS interfaces are used to transfer large amounts of data (e.g. HD video data) via a high speed serial connection to an external location like a video screen.
Wireless connectivity
For multimedia streaming, hands-free calling and A2DP stereo with easy pairing, a highly integrated combination chip that enables Wi-Fi®, Bluetooth®, and GPS/GLONASS is connected to the host processor.

The PCM510xA-Q1 provides 2.1-VRMS ground centered outputs, allowing designers to eliminate DC blocking capacitors on the output, as well as external muting circuits traditionally associated with single supply line drivers.
The integrated PLL on the device removes the requirement for a system clock (commonly known as master clock), allowing a 3-wire I2S connection and reducing system electromagnetic interference (EMI).
The PCM510xA-Q1 family of audio DACs uses advanced current segment architecture to greatly reduce out-of-band noise, which could make the traditional 20 kHz low-pass filter a thing of the past in many automotive audio systems.
The PCM510xA-Q1 family of audio DACs offers up to 20-dB lower out-of-band
noise, reducing EMI and aliasing iPMCn downstream amplifiers and analog-to-
digital converters (ADCs) from traditional 100 kHz OBN measurements all the
way to 3 MHz.

The DS90UH925Q serializer, in conjunction with the DS90UH926Q deserializer, provides a solution for secure distribution of content-protected digital video within automotive entertainment systems. This chipset translates a parallel RGB video interface into a single pair high-speed serialized interface. The digital video data is protected using the industry standard high bandwidth digital content protection (HDCP) copy protection scheme, enabling playback of content-protected media. The serial bus scheme, FPD-Link III, supports video and audio data transmission and full duplex control including I2C communication over a single differential link. Consolidation of video data and control over a single differential pair reduces the interconnect size and weight, while also eliminating skew issues and simplifying system design.

Haptics
Automotive haptics solutions
Easy-to-use, advanced HMI improves safety on the road Solutions for ERM, LRA and Piezo actuators
As automotive in-car infotainment systems become increasingly complex, driver distraction has become a critical issue. Within the infotainment center console, capacitive touch buttons/sliders/knobs are being used to replace mechanical controls in addition to capacitive touchscreen LCDs. A major drawback in the use of these technologies is that they provide no tactile feedback when the driver is navigating through different menus and settings. This leads to the driver taking their eyes off the road to see if their input was accepted. Due to this, the automotive industry has placed a large importance on creating safe and innovative ways to keep the driver's eyes on the road and hands on the wheel. · Touch interfaces are managing an increasing amount of dynamic content and
features · New guidelines published from NHTSA and the SAE set the criteria for maximum
task and glance times · Today's auto interface must be intuitive, easy to use, and offer rich features while
maintaining safety standards and minimizing distractions
Haptics, by definition, refers to the sense of touch and is a technology that adds tactile feedback to electronic devices through the use of vibrations. By adding haptics, your finger will get the impression that you are pressing an actual button. Leading brands use haptics to create compelling, realistic user experiences and enhance driver safety.
