Functional Description

4.1 Functional Description

Programming software here as described is intended for programming the in- ternal control register of the CDCM7005. The software runs under Win- dows98, NT, 2000, and XP. A quick installation is required prior to use. See the Software Installation section.

There are several cases where programming is mandatory.

As a rule of thumb here are some examples:

-Use of active loop filter

-Change of divider ratio or disable of certain LVPECL/LVCMOS outputs

-Select between LVPECL or LVCMOS output

-Change of phase offset, (Delay M/N), or selection of 90’ or 180’ phase shift

-Change of charge pump output current.

-Widening the lock detect window
