Hi,

I need input circuit model for SYNC pins of ADC34J25. What is the IO standard of these pins?

Best Regards,

    mdursun,

    These are LVPECL inputs. The Vcm is at 0.95V, the typ high value is 1.3V and the typ low level is 0.5V.We normally drive this from LVDS output pins of an FPGA and level shift the signal using resistors to get the correct Vcm at the ADC input. See attached EVM schematic.

    Regards,

    Jim
