Synthesizer on FMC carier card v2

antlip

HI!

I have zynq 7030 and PicoZed FMC Carrier Gen2. I want use Synthesizer on FMC Carrier Gen2, and get clock 125 Mhz. I know that this Synthesizer must set up with help I2C. But i don't know how do this.

Who can help me in this issue?

    Hi AntLip,

    Check out the Transceiver Clock Programming Reference Design tutorial, specifically the Experiment 2 section:

    http://picozed.org/support/design/13076/106

    You will need to use IDT Timing Commander to find the updated settings for IDT UFT242 on the carrier card.

    Once you have those settings, you can format the EEPROM contents and use the files in the tutorial to configure the EEPROM with your new frequency settings and then power cycle the board to startup each time with the new settings enabled from the EEPROM config.

    Best Regards,

    Hi, zedhed!!

    Thank's for your reply!

    IDT Timing comander want setting file. Where i can take this file?

    Can i tune Synthesizer with help SDK only?

    Hi AntLip,

    My recommendation is to simply input the clock output target frequencies into IDT timing commander starting from a fresh project.  I have run into some issues in the past when loading old settings files created with older versions of Timing Commander, into newer versions of Timing Commander.  I found that Timing Commander works well when you simply start from a fresh project, input your target frequencies (save your project), and output the settings to an EEPROM configuration to get the HEX that goes into the EEPROM on board PicoZed carrier.  That EEPROM HEX data can be copied/pasted into the SDK project that we provide as part of that reference design.  When you execute that application, the example application we provide will program the EEPROM on board with your new clock configuration and you will have to POR for the new clock configuration to take effect.

    Best Regards,

    Hi AntLip,

    Take a look at that PDF that is included with the Reference Design/Tutorial I pointed out above.  Most of the instructions you need should be in that document included with the Tutorial download.
