Agilent Technologies has introduced software for decoding USB 3.0 SuperSpeed Inter-Chip (SSIC) and MIPI Camera Serial Interface 3 (CSI-3) protocols on oscilloscopes. The new protocol decoders provide design and validation engineers with a fast, easy way to validate and debug their SSIC and CSI-3 interfaces.
SSIC is used for point-to-point communication between chips using the USB 3.0 protocol. The standard was developed by the USB-IF standards body, leveraging the MIPI Alliance MIPI M-PHY electrical layer to transfer USB 3.0 protocol. It allows USB 3.0 intellectual property and designs to be adopted into mobile applications.
The CSI-3 standard is a next-generation camera interface developed by the MIPI Alliance to increase performance throughput and enable a greater feature set than the current CSI-2 standard. It also has better power-per-bit efficiency than the previous specification. The CSI-3 interface runs on top of the MIPI UniPro protocol layer as well as the MIPI M-PHY electrical layer.
Agilent’s N8819A USB 3.0 SSIC and N8820A MIPI CSI-3 protocol decoders are designed to run on 90000A, 90000 X- and 90000 Q-Series oscilloscopes. They decode protocol packets for the SSIC v1.0 and MIPI CSI-3 v1.0 specifications, respectively.
In addition to using the software for startup debugging, R&D design and validation teams can use the software to snoop at traffic on the interfaces. They also provide accurate timing measurements associated with the protocols.
The software supports correlated protocol decode information with the analog waveforms; symbol, packet, frame and payload detail of the protocols; high-speed (HS-BURST) and low-speed pulse-width modulation (PWM-BURST) transmission modes; cyclical redundancy check (CRC) on the packets; and search capability for various frames, sequences and errors.
Used together with N2809A PrecisionProbe software, the protocol-decode software increases design margins and gives engineers increased confidence in their product performance. The N8805A USB 3.0 protocol decoder, N8808A UniPro protocol decoder and U7249B transmitter conformance software package are also available.
