Multiplying with 11 using PIC

[eltra11]

Hi Richard , Hi Henrik
You enormously help me in solving to approach to the task on the right way by conclusion that neither CCP or NCO should not lead to the solving of the problem.
As one solution I shall try is to solve it with PLL – CD74HC4046A.Here the PIC should be used to detect input frequency and accordingly to switch on or off elements in VCO low pass filter to obtain the input frequency range from 1 Hz to 1 MHz.The multiplication should be realized by 11 time divider in between VCO output and Comparator Input of CD74HC4046A.
I ordered the chips accordingly and it will take some time to get it and then I shall make the test.

what came to my mind first for that was PLL..... phase-locked-loop that does exact frequency multiplication using divide by N as the multiplier. One problem would be the 'dynamic range' of 1 million for the 11 to 11MHZ. The PIC could switch in 1 of 2 or 3 PLL's for workable operating ranges.
