This section presents an approach to architecting the dc-dc conversion stage to handle the transients on automotive battery rail. Following topologies are covered:
- Always-on boost + buck
- On-demand boost + buck
- Buck + post boost
Pro/cons of the different approaches are also discussed.

This video presents a short overview of automotive frond-end and the transients tackled by the frond-end power conversion stage connected to an automotive battery rail.
As the number of complex electronic features in vehicles increase, body control modules (BCMs) are rapidly evolving to keep up. All semiconductor devices in a BCM have one thing in common – they all need power. This training series will go over the various power topologies needed in a BCM in a vehicle.
In this four-part video series, our experts answer questions around the biggest trends impacting the automotive industry—electrification, automation, connected car and integrated cockpit—and how they are impacting your system design, including:
- How is vehicle electrification reducing emissions?
- What level of autonomy is the most important right now?
- What is driving the evolution of the digital cockpit?
- How does the connected car communicate with its surroundings?
Creating a Robust Interface Between J6 and FPD-Link .
This video series provides an overview of diagnostic capabilities of FPD-Link III and basic tips to simplify troubleshooting.
The DS90UB953/954 System Design & Operation video series offers training for FPD-Link III devices for ADAS. FPD-Link III devices such as the DS90UB953-Q1/ DS90UB954-Q1 support sensor use over serial link for Advanced Driver Assist Systems (ADAS) in the automotive industry. In this training series, we will guide you through step-by-step procedures to initialize and bring-up the “Sensor-Serializer-Deserializer-ISP” link to an optimal performance level.
This section analyzes the link between the 953 and 954 and establishes how to identify the health and operation of the link. Since the link between the 953-954 is the most fundamental link used to communicate between devices, it is often checked first.
Specifically, this section discusses: Back Channel configuration, Built in Self Test (BIST), Adaptive Equalization (AEQ), and Channel Monitor Loop (CMLOUT)
This section discusses what frame synchronization (FrameSync) is and how to configure in on the 953 and 954 and how CSI2 data is transferred across the link from the 954 to the ISP/SoC
Specifically, this section discusses: Frame Synchronization (FrameSync), Controlling 953 GPIOs locally and remotely via I2C, Unsynchronized and synchronized sensors, Internal and External Frame Sync, Port Forwarding, Accessing Indirect Registers, and Pattern Generation on 953 & 954
Understanding what hardware and software settings are important is critical to establishing a foundation for the 953/954 system. These settings can occur during or after power up and may need to be changed via software. As a result, these settings are routinely checked and verified before checking any of the other links in the system.
Specifically, this sections discusses: Diagnostics post power up, Mode and IDX Pins, Clocking Modes between the 953/954, Aliasing, I2C Pass Through, Port selection on 954, Analog Launch Pad (ALP), and Successful I2C Communication
This section discusses how design a 953/954 using Power over Coax (PoC), and various hardware checks and concepts that need to be considered when analyzing a 953/954 system.
Specifically, this section discusses: Power Over Coax (PoC), AC Coupling Capacitors, PoC Inductors, Typical PoC Schematic, Critical Signal Routing, I2C Pullups, Loop Filter Capacitors on 953, Insertion Loss, Return Loss, and Time Domain Reflection (TDR) measurements.
This introduction video will give the background on FPD-Link III devices, such as the DS90UB953-Q1/ DS90UB954-Q1; the device's role within Advanced Driver Assist Systems (ADAS) in the automotive industry; and explain their broad appeal to engineers of all experience levels. This is fundamental to diving deeper into a 953/954 system, as well as, the links within the system.
