Protocol analyser accelerates ADAS development
A flexible and robust analyser designed to ease troubleshooting and support the development of complex imaging and detection systems for mobile displays and cameras has been launched by Teledyne LeCroy. The Envision X84 analyser supports both MIPI C-PHY/D-PHY and MIPI Camera Serial Interface (CSI-2)/MIPI Display Serial Interface (DSI-2) in a single platform, providing device designers and system integrators more design flexibility, control and expediency.
MIPI interfaces and busses are used extensively in both cameras and mobile displays in devices and systems. MIPI CSI-2 supports high-performance video (1080p, 4K, 8K and beyond), and high-resolution photography and is increasingly used to transport camera images for advanced driver assist systems (ADAS) in the automotive environment.
MIPI DSI-2 supports ultra-high definition (4K and 8k) mobile displays and specifies the physical link between the chip and display in devices such as smartphones, tablets, AR/VR headsets and connected cars.
The MIPI C-PHY and D-PHY busses provide high-throughput performance in connecting displays and cameras to their application processors.
Design and test engineers and system integrators can use the Envision X84 analyser to test performance and conformance of MIPI CSI-2 for cameras and image sensors and MIPI DSI-2 for mobile displays.
The instrument will help to accelerate the design and development of mobile devices, application processors, and systems on chip (SoCs), especially when both C-PHY and D-PHY are implemented in the same chip.
The Envision X84 protocol analyser has up to 3 lanes of C-PHY at 3Gsym (24Gbps) and up to 4 lanes of D-PHY at 2.5Gbps or 10Gbps. This includes support for MIPI CSI-2 and MIPI DSI-2 protocols.
It performs protocol checking from PHY level through protocol-level events, including low-power modes and reads/writes.
Complex, event-based transaction captures are coupled with 2.5-ns event timing resolution for detailed debugging.
The system supports all camera and display packet types and data formats as well as command and video modes.
