Fpd link iii deserializer A27_MAX96706

Application of Industrial Deserializer board in testing of cell phone camera module.

1. Key role in the test process
Protocol conversion: High-speed differential signals from cell phone camera modules (e.g. MIPI CSI-2 interface) need to be converted to USB or Ethernet signals by Deserializer boards for processing by test equipment (e.g. computers). For example, Dothinkey's Image Grabber GQ4 supports the D/C-PHY interface, which enables synchronized four-camera testing through fiber-optic transmission.
Image quality analysis: After the Deserializer board converts the RAW data into a displayable image, the test software (e.g. Imatest) analyzes parameters such as resolution, noise, distortion, etc., to ensure that the module complies with standards such as ISO 12233 and ISO 15739.
Protocol compatibility verification: For new protocols (e.g. CPHY V3.0), Deserializer boards need to verify the communication stability between the module and the host. Dothinkey upgraded the FPGA firmware to support CPHY LRTE mode and solved the transmission problem caused by high-frequency LP signal.

2. Typical Test Scenarios
3D camera test: For structured light or ToF modules, Deserializer boards need to process laser drive signals (e.g. VP20 Image Grabber supports nA-level photocurrent measurement) and image reception data to ensure 3D imaging accuracy.
High-resolution module testing: For example, Deserializer boards supporting 8K resolution (e.g. RK3588 industrial core board) can process 4320P video streams in real time to verify the bandwidth performance of the module.
Multi-Camera Collaboration Test: Deserializer boards need to process data from multiple cameras synchronously to ensure that the picture stitching or stereo vision functions properly.

3. Integration with Dothinkey products
Integrated decoding function with Image Grabber: Dothinkey's Image Grabber (e.g. UC930) has a built-in FPGA and ASIC chip, which supports automatic switching of MIPI CSI-2 and DVP interfaces, and outputs processed data via USB3.0.
Flexible Protocol Adaptation: Dothinkey quickly adapts new functions, such as CPHY LRTE mode, to the protocol requirements of different sensor manufacturers by upgrading the FPGA logic.

Industrial Deserializer board is the core component of cell phone camera module testing, which includes protocol conversion (e.g. MIPI CSI-2 to USB), data decoding (e.g. RAW to RGB) and signal optimization (e.g. noise filtering).

Dothinkey and other vendors use FPGA technology to realize flexible protocol adaptation and support high-resolution, multi-camera collaborative testing to meet the needs of mass production in consumer electronics, automotive electronics and other fields. When selecting a Deserializer board, it is necessary to choose a Deserializer board with corresponding interface, bandwidth and processing capability according to the test scenarios (e.g. 3D camera, 8K video) and protocol requirements (e.g. CPHY LRTE).
