Acute Technologies MIPI D-PHY Option

Product Code: BFO-PHY

Professional MIPI D-PHY Decode for CSI-2 and DSI Add-on option for Acute BusFinder protocol analysers to capture, decode and visualise MIPI D-PHY traffic from Low-Power to High-Speed transitions. Interface Standard Lanes Data Rate Display Formats Error Checks MIPI D-PHY V1.2 1 + 4 (CLK, D0–D3) Up to 2.0 Gbps per lane RGB, YCbCr, RAW, DSC ECC/CRC count & report What it does Decodes CSI-2 1.3 and DSI 1.3 packets with DCS 1.3 command analysis. Captures from LP init through HS data, with filters to ignore image payloads and extend capture depth. Restores and displays image frames; provides porch statistics for timing analysis. Searches by packet type, virtual channel, data ID or error; compiles command statistics. Detects TE (Tearing Effect) signalling; exports logs to TXT/CSV for post-processing. Way Station Pinout Pair Signals Notes CLK (Diff) CLK+ / CLK− Differential clock input D0 (Diff) D0+ / D0− Data lane 0 D1 (Diff) D1+ / D1− Data lane 1 D2 (Diff) D2+ / D2− Data lane 2 D3 (Diff) D3+ / D3− Data lane 3 TE (Optional) TE Tearing Effect detection channel Signal access: keep solder pigtails under 5 mm; on the DUT, place a 100 Ω termination and connect to the end-tip with ~3 cm coax to minimise loading.

Wiring Quick-Start Power and connect the BusFinder; fit the D-PHY Way Station to Slot-B and SMPM coax leads to the end-tips. Solder ultra-short pigtails to CLK and D0–D3 differential pairs at the DUT test pads; add optional TE lead if required. Launch BusFinder software, select MIPI D-PHY DSI/CSI mode, verify Way Station LEDs, then arm capture in LP mode. Use Data Filter to suppress image payloads, enable ECC/CRC counters, and configure triggers on specific packet types.
