Im building jitter measurer for 2MBit signal.

                     --------------
                     | estimating  |
                     | clock       |
                     --------------
                      |           |
     ----------       |           |         -------------
-IN--|Extract. |------             ---------| Phase      |
     |clock    |----------------------------| detector   |
     ----------                              ------------

Estimating clock will be in different time periods.
I have already Extracted clock from 2MBit HDB3 signal.
I think that i will estimate clock on PLL changing FPD filter for different
time periods.

The hole problem now is to build Phase detector for such big jitter.
