Lock time depends on PLL loop bandwidth. Wide loop bandwidths lock quickly. Narrow ones slowly.

For fast locking applications the ADF4193 is the fastest part we have.

Hi,
I have a current prototype design with a ADF4154, the ability to achieve quick settling (<20us) using the fast-lock feature is critical, for production I would like to add a lock detect indication and so am considering a replacement part.

If you are looking for a board similar to the EV-ADF4196SD1Z, with an on-board VCO, then look at the EV-ADF4193SD1Z.
However, the ADF4193 and ADF4196 are quite specialized PLLs. If you are just looking for a standard PLL, then you could look at the EV…
"I understand about disabling band select (maybe) for small frequency steps, but can it be disabled while stepping through the entire frequency range above? That would be good..."
Defeats the purpose of band select in the first place...
