Automotive Audio I2S over Coax Class D Amplifier Reference Design
This reference design is an I²S/TDM-based: low-cost: easy-to-use alternative to fiber optics/analog copper wire for connecting an automotive (sound) control panel to an output stage/power amplifier. Supporting I²S as well as TDM: it is capable of transmitting digital audio signal to 16 independent channels of speakers with each channel output of 80W at 4Ω. It also supports bidirectional communication with the control unit or processor via I²C: over a single shielded twisted pair (STP) or coaxial. Furthermore: the TIDA-00223 reference design enables fast implementation with power supply included: and it has all the protection and diagnostics requirements needed in modern cars.

Power Solution for Aptina Image Sensor in Automotive Camera Modules Reference Design
The reference design provides a compact power solution (20x20mm board size) for the Aptina AR0132 image sensor in automotive camera modules. The design comes with a power supply board and a filter board. The power board has two sync-buck regulators: LM34919C and TPS62231: to provide 1.8V and 2.8V outputs. RC output filters are designed for the core: analog and I/O supply rails required by the image sensor in order to reduce the ripple and ensure proper power-up sequencing. The input voltage range is from 4.5V to 50V suitable for 12V automotive battery supply. The filter board is designed to enable the power over coax cable configuration: which allows transferring power and the FPD-Link III signal over one cable. There is also an input line filter option on both boards in case the power-over-coax configuration is not desired.

CISPR 25 Class 5 Rated 1.5W Automotive Power Reference Design
The PMP9361 reference design provides an EMI optimized 1.5W power supply design for automotive applications. This design features the LM34919C: a 50V: 600mA buck regulator: AEC-Q100 qualified: with a switching frequency up to 2.6MHz and in ultra-small 2x2mm DSBGA package: making it suitable for automotive applications. The power supply generates a 3.3V output at 500mA: and the switching frequency is set at 2.1MHz to avoid AM bands interferences. The design comes with the input EMI filter to suppress the conducted emissions. It is tested under the CISPR 25: the automotive EMC standard: and the result is compliant with the Class 5 conducted emissions standard.
