The Introspect MIPI D-PHY and C-PHY Analyzer is an ultra-portable high-performance instrument that supports characterization and validation of MIPI D-PHY and C-PHY transmitter ports on the same device. The analyzer operates at speeds of up to 8.5 Gbps for MIPI D-PHY and 6.5 Gsps for C-PHY, combining analog signal measurement capabilities with complex capture and comparison modes for complete D-PHY and C-PHY packet analysis. This instrument utilizes the highly versatile Introspect ESP software environment, which includes a complete set of DSI-2 and CSI-2 video frame extraction tools. The software automates testing for packet error rates, protocol timing analysis, and MIPI CTS.Key Features of the Analyzer:D-PHY Physical Layer: four D-PHY lanes with integrated LP/HS signaling and support for a continuous range of data rates up to 8.5 GbpsC-PHY Physical Layer: four C-PHY trio receivers with integrated LP/HS signaling and support for a continuous range of symbol rates up to 6.5 GspsD-PHY C-PHY and Protocol Layer: fully supports CSI-2 and DSI-2 pixel formats, DSI-2 DSC and V-DCM decompression, and DSI Display Command Sets (DCS)D-PHY Physical Layer Analysis: analog waveform capture for HS and LP with precision time stamps for physical layer eventsC-PHY Physical Layer Analysis: analog waveform capture for HS and LP, complete C-PHY decoding (HS wire, wire state, symbol, and data), precision time stamps for physical layer eventsProtocol Layer Analysis: packet error rate testing, full video frame extraction and analysis, and sophisticated capture modes triggered on physical layer and protocol layer eventsHardware Connections:Provides SMA: The analyzer can function as a standard receiver, offering a standard SMA interface to connect with the device under test, receiving signals from D-PHY/C-PHY TX to check compliance with relevant protocol specifications, error rates, and CRC/ECC related errors.Provides RSH1/RSH2: Introspect offers RSH1/RSH2 to diagnose issues in system-level products (SOC MIPI C-PHY/D-PHY TX connected to a display or SOC MIPI C-PHY/D-PHY RX connected to a camera).Special Features:1. Eye Diagram Measurement Function: – Through the built-in signal eye diagram detection function, it can preliminarily confirm the signal quality on each transmission channel, further identifying whether issues arise from abnormal signal quality affecting DSI/CSI protocols or from the CSI/DSI protocol layer itself. – The built-in eye diagram measurement function of the analyzer provides immediate tools for confirming signal quality.
2. Analog Capture Function: – The analyzer provides innovative signal capture capabilities, allowing for the capture of LP and HS signals, assisting engineers in clarifying potential signal quality issues, as shown in the figure below. – Application Scenario 1: Skew issues between channels By capturing the LP Sequence entering the HS Burst waveform, multiple channel waveforms can be captured simultaneously, where severe phase shifts between adjacent channels may cause reception failures. – Application Scenario 2: Channel signal noise causing synchronization code SOT loss Multiple HS signals can be captured simultaneously across channels, and when signal quality issues arise on a specific channel, the captured waveforms can detect signal quality problems on that channel.
3. PER (CRC Packet Error Rate) Signal Quality Stability Measurement Function: – Through the PER (Packet Error Rate) measurement function, real-time monitoring of MIPI D-PHY/C-PHY TX image transmission can be conducted over extended periods, ensuring the stability of signal quality on the D-PHY/C-PHY TX link.
