JTAG Implementation

    I am about to embark on the production version of a design which uses the BCM53286 switch and BCM5482S GPHY devices.

    Our prototype PCB has been validated and some of the circuitry deemed unnecessary has been removed from the board which has freed up enough space to add a connector for JTAG support (there wasn't room for it in the prototype board).

    I would like to use one JTAG connector and daisychain together the BCM53286 and BCM5482S devices. This is standard practice and supported in the JTAG standard, but do you foresee any problems in doing this with the Broadcom devices?

    Hi Darren,

    It supports JTAG daisychain connection and no problems.
