How do we design a circuit that will enable greater than 12 inches of ribbon cable between the EVAL-ADIS and the device-under-test (DUT)?
The EVAL-ADIS has two interface connectors, which both provide access to SPI interface on the DUT. J4 is a 24-pin, 1mm-pitch connector that mates to all IMU products. J1 is a 16-pin, 2-mm connector that supports connection with breakout boards, such as the ADIS16488/PCB. The PDF file attachment provides reference design materials for an internal design, which extends the SPI communications to a length of approximately 2 meters in an internal test system.
The gerber files for this reference design are in the attached zip file. Use these files at your own discretion. While these gerber files were used in our internal testing, with success, ADI accepts no responsibility for any misue of these files.
