Carrier card V2 default frequencies

halc

Hey all,

I am currently starting developing on the picozed with carrier card v2. There is the IDT 8T49N242-006 clock synthesizer IC which provides the MGT and PL clock for the Zynq.

Does anybody knows the default frequencies of Q2 and Q3 output of the IC?

    Hi there,

    From the factory, the clock is not set.  You will need to use "Transceiver Clock Programming Reference Design" in order to setup the clock.  There are 3 examples included. 

        *MUX in a clock from the PCIe card edge
        *MUX in a clock from the FMC connector
        *The "default" configuration used in all the provided reference designs, 250MHz.

    There is a set of these for each of the PicoZed transceiver based SOMs (PZ7015/PZ7030).  Each of these files are bootable BIN files that you can use to directly program the part without needing to run the entire reference design.  I would suggest you follow the instructions provided in the design to properly configure the card for SDCARD boot as well as validate that the programming is a success!  You can also customize the design with your OWN frequencies!

    If you use the 250MHz BIN file, the chip is configured for a 250MHz clock on both Q3 and Q4.

    You can locate the reference design here:
