Agilent launches protocol analyzer for mobile apps

Agilent Technologies Inc. has introduced its U4431A MIPITM M-PHY protocol analyzer for next-generation mobile computing applications. This new protocol analyzer gives engineers in R&D and manufacturing deep insight into MIPI M-PHY-based designs.

The M-PHY specification includes four-lane, 6.0-Gbs options. The U4431A offers up to 16 GB of analysis memory on each lane, allowing designers to capture tens of seconds of system traffic, even at these high speeds. In addition, the Agilent U4431A offers “Raw Mode,” a feature that lets designers see the time-correlated 8b/10b data that underlies each protocol. These states can be displayed as a waveform or listing, providing insight into how a packet is formed at the physical layer. This visibility extends throughout the M-PHY protocol stack, allowing error detection from the physical layer to the link and from the transport layers to the high-level application layer. These views allow engineers to unravel data as it travels throughout the entire transmission process.

The U4431A offers tools to isolate and unravel specific events on the bus. Real-time triggers allow the detection of errors at each layer of the protocol, filters focus analytic tools on specific types of traffic, and traffic overviews and measurement markers help designers understand traffic from entire bursts to nanosecond-resolution detail.

The modular AXIe blade form of the U4431A allows users to analyze multiple M-PHY busses simultaneously. These M-PHY busses can be time-correlated with MIPI D-PHY CSI-2 and DSI-1, PCIe, DDR and HDMI busses, or even generic high-speed logic analyzer modules. Designers can purchase as many lanes and as much memory and protocol support as they need today, and upgrade in the future.

The U44431A MIPI M-PHY protocol analyzer can be ordered now and is expected to ship in September. Prices start at approximately $100,000.
