MIPI D-PHY Multilane Trigger and Protocol Decode
Emerging serial bus standards in the wireless mobile industry have created the need for equipment to debug and test MIPI D-PHY. The MIPI D-PHY protocol application enables faster and better development of wireless mobile products employing CSI and DSI architectures of the MIPI technology. The protocol analysis application enables teams to quickly move from the physical layer to protocol layer measurements and includes software-based triggering.
These ISI Channels can be used to emulate channel losses in receiver test setups. A choice of 8 PC board traces with different lengths can be inserted into the signal path. The 8 trace lengths range from 7.7 inches (196 mm) to 34.4 inches (874 mm). By cascading the traces within one box or with the other box a wide range of channels can be emulated with very fine resolution steps. With their small size, the ISI channels can be located close to the device under test. The cascadable ISI channels are complemented by Keysight’s compliance channels for SATA, DisplayPort, PCI Express, and HDMI
MIPI C-PHY Trigger and Protocol Decode
C-PHY is a MIPI physical layer (PHY) standard that provides high-throughput performance over bandwidth-limited channels to connect displays and cameras to an application processor. The standard provides a PHY for both MIPI Alliance’s Camera Serial Interface (CSI-2) and Display Interface (DSI-2) specifications. This enables engineers to scale their implementations to support a wide range of higher resolution image sensors and displays while keeping power consumption low. However, because the C-PHY supports two application layers, engineers implementing a C-PHY interface must be able to see a device’s signal integrity and protocol data to ensure it conforms to the MIPI specification.
With C-PHY, seven consecutive symbols are used to transmit 16 bits of data over a minimum of 3 wires (one lane), after encoding. Troubleshooting C-PHY-based applications can, therefore, be time-consuming and error-prone because the engineer has to manually scroll through the waveform looking for regions of interest.
Keysight’s D9110MCDP software extends the capability of Infiniium oscilloscopes, minimizing the time required for debugging and testing designs with CSI-2 and DSI-2 interfaces.
