• RE: LTC6945 EVB question

    If you are using integer mode (LTC6945), the LTC6946 would be the lower cost option with integrated VCO.  LTC6948 can be an integer or fractional part.

  • AD9958: output voltage level?

    Dear support.

    In my design I am evaluating the possibility to involve an AD9958 as DDS.

    The output of the DDS is in the range 90 - 180 MHz. Each output is transformed in single-ended by means of a Balun (TCM4-6T), and than filtered with a Band Pass…

    Dear support.

    Got no ans in DDS section, I try again posting here.

    Sorry for doubling.

  • RE: LTC6957 parallel clock tree

    Hi Daniel,

    One other thought is the LTC6954.  It has 6 outputs pins (3 differential, or 6 CMOS, or some combination CMOS/differential).  It is in the same family as the LTC6957, but with more outputs and its programmable.  If you were thinking of using CMOS…

  • LTC694x Loop Filter Design and Simuation

    What loop filter design tool should I use for LTC694x PLLs and PLL/VCOs? 

    The short answer is:

    LTC6945, LTC6946: PLLWizard

    LTC6947: FracNWizard

    LTC6948: Either FracNWizard or ADIsimPLL
