External phase detector with MAX038

    Hello everybody,

    I would like to use the MAX038 as a sinewave generator. The output
    must be in constant phase with an external square wave signal: phase
    between output and input = 0º = constant within the lock range. My
    input signal will change from ~1MHz to ~1.5MHz.

    Can I use the Phase Comparator 2 of the PLL4046 as external phase
    detector for the MAX038 and then have the requirements that I desire?

    In the data sheet of the MAX038 figure 5, there is a "frequency phase
    detector", but I am not sure this is identical to the Phase Comparator
    2 of the 4046. (figure 4 shows a phase detector similar to the phase
    comparator 1 of the 4046, but I don't want to use that one).

    Thank for your answer

    Find something made by *any* other company.
    Maxim has a bad habit of not making a large number of their advertised
    They aer so bad that a nnumber of distributors actually refuse to
    carry them.
    But if you have tens of thousands of dollars and 6-14 months to
