Other Parts Discussed in Thread: DS90UB913Q-Q1, DS90UB913A-Q1
Hello,
 
Please let me know about DS90UB913Q/914Q-Q1 and DS90UB913A/914A-Q1.
 
(1) Connector Parts No. of DS90UB913Q-Q1,914Q-Q1 EVM Rev.2
Please see the attached files as schematics of DS90UB913Q,4Q EVM rev2.
In these schematics, there are the "ROSENBERGER_HSD_CON"  as connector but we can't find the parts number of this.
Could you please kindly let me know the parts number for boads and cable ?
If there are BOM list , please let me know.
 
(2) Recommended Cable and Connector No. for our oreder.
Please let me know recommended connector parts number for DS90UB913A,914A-Q1?
I need connector information for differential, single-end , cable and board.
 
Best Regards,
Ryuji Asaka

    Rosenberger are a German connector manufacturer, and a catalog of their 'HSD' connectors can be found here:

    http://rosenberger.de/documents/headquarters_de_en/ba_automotive/HSD_Catalog_2014.pdf

    The HSD connector supports two differential pairs per cable.  The particular connector used on the 913/914 boards is the D4S20D-40ML5-Y

    When operated in single ended mode with COAX, the connector that we most often use is another Rosenberger connector, known as FAKRA.   This part number is 59S20X-40ML5-Y.

    Hello Mark san,
     
    Thank you very much for your prompt reply.
    I understood that the HSD connector and the FAKRA connector are recommended due to these are Automotive standards.
    I have additinal questons.
     
    -Q1 : DS90UB913/4A-Q1 Connectors in User’s Guide
    DS90UB913/4A-Q1 EVM boards have SMB connector mounted as shown in attached file page1.
    I think that these are standard SMB connectors.
    Can I use these EVMs by coaxial cable witch has SMB connectors ?
    If yes, please let me know the orderable cable for these connectors?
     
    -Q2 : DS90UB913/4Q-Q1 Connectors in User’s Guide
    Please see the attached file page2.
    I think that we need special cable for these HSD connectors.
    Could you please let me know the connector parts number of cable which can connect D4S20D-40ML5-Y?
     
    -Q3 : Connector name between schematics and BOM.
    There are the J1 of SMA bulkhead in P.22 and P.26 of the User's Guide(SNLU135) .
    Are these parts name typo of SMB ?
     
    -Q4 : Current EVM
    I have the two EVMs of DS90UB913A-Q1 as attached image.
    Right side EVM is latest one which has FAKRA connector(59S20X-40ML5-Y) and TPS65320.
    Are all latest EVM has FAKRA connector and TPS65320?
    If yes, could you please let me know the orderable cable woth FAKRA  female connector for 59S20X-40ML5-Y ?
     
    Best Regards,

    Q1:  The Rosenberger FAKRA connectors are mechanically compatible with SMB connectors.  The FAKRA connector has an additional plastic cowl which adds a lock to the connection, so cables do not come loose with vibration, and it makes the connection more water resistant - both requirements in the automotive environment.  In the lab, you can intermix SMB and FAKRA connections.

    Q2:  When using the HSD connections, we generally use cables that we obtain from Rosenberger.  They sell connector/cable assemblies in a variety of different lengths.

    Q3:  The EVK is intended for evaluation purposes, and is therefore made to be as flexible as possible.   The PCB footprint that we used can be used either with SMB, or SMA connectors, and we use either of those for COAX evaluations, depending on what the specific system requirements are.

    Q4:  Current DS90UB913EVMs are fitted with the FAKRA surface mount connector as shown on the right side. 

    Q5: A common cable which we order which has the FAKRA connectors on it comes from an american company: Pasternack, and can be found here:
