MIPI CSI-3 Description and Features

Camera Serial Interface version 3.0 (CSI-3) standard was developed by MIPI Alliance to increase performance throughput and greater feature set from CSI-2 standard. The CSI-3 interface runs on top of the MIPI M-PHY electrical layer as well as the MIPI UniPro protocol layer that is also developed by MIPI Alliance standard body. The serial bus interface provides content-rich points for debug and test. However, since this protocol transfers bits serially, using a traditional oscilloscope has limitations. Manually converting captured 1’s and 0’s to protocol requires significant effort; can’t be done in real-time; and includes potential for human error. Also, traditional scope triggers are not sufficient for specifying protocol-level conditions.

Extend your oscilloscope’s capability with the Keysight Technologies, Inc. CSI-3 protocol decoder

This application makes it easy to debug and test designs that include CSI-3 buses using your Infiniium Series oscilloscope.

– Set up your scope to show CSI-3 and UniPro protocol decode in less than 30 seconds.

– Get access to a rich set of integrated protocol-level triggers.

– Save time and eliminate errors by viewing packets at the protocol level.

– Use time-correlated views to quickly troubleshoot serial protocol problems back to their timing or signal integrity root cause.

The following are the CSI-3 protocols and features that will be supported by the application.

1. Support CSI-3 v1.0 decode and triggering

2. Can be used together with the N8808A MIPI UniPro protocol decode to show both CSI-3 and UniPro packets

3. Decodes High-Speed (HS-BURST) and Low-Speed Pulse Width Modulation (PWM-BURST) modes

4. Supports search capability for Host and Device transactions as well as symbol sequence and errors.

MIPI CSI-3 Setup, Protocol Triggering and Search Capabilities

Get access to a rich set of integrated protocol-level triggers.

The application includes a suite of configurable protocol-level trigger conditions specific to CSI-3. When serial triggering is selected, the application uses software-based triggering.

With software-based protocol triggering, the oscilloscope takes signals acquired using either oscilloscope or digital channels and reconstructs protocol frames after each acquisition.

It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.
