Teledyne Lecroy's Envision X84 analyzer.

Teledyne Lecroy’s Envision X84 analyzer supports the MIPI CSI-2 and MIPI DSI-2 protocols on C-PHY or D-PHY

  • Teledyne LeCroy offers the Envision X84 protocol analyzer that supports the MIPI C-PHY/D-PHY and MIPI CSI-2/DSI-2 interfaces.
  • This analyzer is designed for applications that develop and debug imaging and detection systems, such as mobile screens and cameras.

Envision X84 is, according to Teledyne LeCroy, the first analyzer on the market capable of supporting MIPI C-PHY/D-PHY and MIPI Camera Serial Interface (CSI-2)/MIPI Display Serial Interface (DSI-2) within a single platform.

The Envision X84 analyzer is designed to provide performance and compliance testing of MIPI CSI-2 links for cameras and image sensors and MIPI DSI-2 for mobile displays, especially when the C-PHY and D-PHY subsystems are implemented in the same chip.

This instrument has a C-PHY and D-PHY capture capability with up to 3 C-PHY at 3Gym (24Gbps) channels and up to 4 D-PHY channels at 2.5Gbps or 10Gbps. It supports the MIPI CSI-2 and MIPI DSI-2 protocols.

Envision X84 verifies protocols from the physical layer (PHY) to protocol level events, including low power modes and read/write. Complex event-based transaction captures are coupled with a time resolution of 2.5 ns for detailed debugging. The system supports all types of camera and display data packages and formats, as well as control and video modes.

MIPI interfaces and buses are used for the integration of camera and imaging components in mobile devices. MIPI Camera Serial Interface (CSI-2) allows the transmission of video and images in high resolution (1080p, 4K, 8K and above). They are also used for image transmission from on-board cameras in advanced driver assistance systems (ADAS) in the automotive sector.

MIPI Display Serial Interface (DSI-2) supports the very high definition (4K and 8k) required by new and future mobile displays. It specifies the physical link between the chip and the screen in devices such as smartphones, tablets, AR/VR headsets and connected cars.

The MIPI C-PHY and D-PHY buses have the appropriate specifications to support high-speed connections from displays and cameras to their application processors.
