DS90UB954-Q1EVM: Schematic and board layout files needed and how to configure the board without POC filter options

Part Number: DS90UB954-Q1EVM
Other Parts Discussed in Thread: DS90UB935-Q1, , ALP


I am using the DS90UB954-Q1EVM REV E2 board. I would like to interface the DS90UB935-Q1  sterilizer without power over coax option. I look for the schematics and board files of the EVM , not able to found, please shared them and suggest the configuration settings for interfacing the 935 serilizer with out poc filter. like I have the application like the video data comes through the 935 to display. 

  • Hello Balakrishna,

    To disable power over coax on the DS90UB954 EVM Rev E2, please remove the jumpers from headers J16 and J14 in this case. These headers select the PoC voltage for the two ports. Leaving the headers open will disable PoC between the 954 and 935 EVM. The DS90UB935 EVM will be powered with it's own supply. 

    Do you have access to the 954 EVM User's Guide? Schematic and layout figures are supplied at the end of the document. Is there a need for the files or does this information fulfill what is needed? 

    Please let me know if you have any additional questions. 



  • Thanks for the reply.

    When I connect the EVM with the 935 sterilizer, ALP shows 913 as detected. How could I get the 935 device, please suggest. And the "PASS" and "LOCK" diodes in the EVM not glowing. please suggest any setting changes to be done. 


  • And I would like to capture the link transitions through the CMLOUT functionality, please let me know how to enable the CMLOUT functionality in the 954 EVM board.

  • Hello Balakrishna,

    The partner information should update automatically when lock is detected on the deserializer. Are you able to read the remote registers? Are both EVMs powered separately?

    Additionally, the datasheet for the 954 provides the following information on configuring CMLOUT for RX Port 0. The overall configuration will depend on the port selected.
