ML605 FMC LPC clock signals

Hi,

 

    Does anyone know how to understand the clock signal pins? I need to know about the pins which goes back to FPGA and coming out of FPGA (except differential data pins which are going to the target device). A typical application would be a DAC to FPGA interface where I have to supply clock signals to the DAC. What I am not sure about is which pins are supplying the clock signals to the DAC?

 

My FPGA device is Virtex- XC6VLX240T-1156  (on ML-605)

 

Thanks :-)

Re: ML605 FMC LPC clock signals

mm,

Depends.

The ML605 manual details what pins on the FMC connect to what pins on the FPGA device. If you need a clock on a pin (or a pair of pins), you program the FPGA device to place the right clock standard, of the right frequency, on the right pins. One may use the multi-mode clock manager (MMCM) to convert a clock on the device to the frequency one needs externally.

What FMC daughter card are you looking at using? It will already have the pins assigned, and there is probably a .ucf file suggested that defines how the pins on the FPGA device should be programmed....

If the FMC name includes M2C then it goes from the FMC Module to the Carrier Card.

If the FMC name includes C2M then it goes from the Carrier Card to the FMC Module.

If the FMC name has neither M2C nor C2M then it can be either direction.

 

If the FMC name includes CC and it is connected to a FPGA then it should be connected to a Clock Capable input pin.

Quick question: Carrier Card?

If the FMC name includes M2C then it goes from the FMC Module to the Carrier Card.

Pardon my ignorance, but -- in the context of this thread -- is the ML605 board the "Carrier Card" ?
