Support for LP Voltage Measurement Image Frame Grabber

The LP voltage measurement supported by the Dothinkey GX4 Image Frame Grabber means that the Image Frame Grabber is able to measure the voltage in the LP (Low Power) state in the MIPI PHY interface. The following is a detailed description of LP voltage measurement:

Definition
The MIPI PHY interface is a common mobile industry processor interface physical layer specification used to connect the processor to peripheral devices such as cameras, monitors, etc. In MIPI PHY interface, there are two modes of data transmission, HS (High Speed) and LP mode, which is a low-power communication mode mainly used for transmitting control signals and a small amount of data.LP voltage measurement is to measure the voltage of the relevant signals of the MIPI PHY interface in LP mode to ensure that the voltage value is within the specified range, so as to ensure normal communication and the stable operation of the interface and equipment. to ensure normal communication and stable operation of the interface.

Measurement Range and Accuracy
Measurement Principle
LP voltage measurement is mainly through the precision voltage detection circuit in the Image Frame Grabber, sampling and amplifying the voltage signal output or input from the MIPI PHY interface in LP mode, and then using the analog-to-digital converter to convert the sampled analog voltage signal into a digital signal, and then finally through the built-in measurement algorithms to process and analyze the digital signal, so as to get the accurate LP voltage value.

Importance and Application Scenarios
Quality Inspection: During the manufacturing process of MIPI devices, LP voltage measurement can be used to detect whether the LP voltage of chips and modules meets the design requirements and industry standards, so as to timely detect quality problems in the production process and ensure the consistency of product quality.

Troubleshooting: When MIPI devices have communication abnormalities, functional failures and other problems, LP voltage measurement can help engineers quickly locate the cause of the problem, determine whether it is the interface circuit, power supply or the chip itself, so as to carry out targeted maintenance and debugging.

R & D debugging: In the R & D stage of MIPI equipment, R & D personnel can optimize and adjust the circuit design and power management strategy based on the LP voltage measurement results, in order to improve the performance and stability of the equipment, and to ensure that the equipment can be reliably operated under different operating conditions.

Compatibility Test : Since MIPI devices from different vendors may have certain differences, LP voltage measurement can assess the compatibility between different devices to ensure that they work properly during connection and communication, and avoid compatibility failures caused by voltage mismatch and other issues.
