HMC833 Update Frequency speed

Hello,
I need a PLL with fast fast frequency update (<40-50µs) and a frequency output up to 6GHz.
I am looking on HMC833 and LMX2592 components (from Texas Instrument).
I know differents frequencies I needed, and I can store config settings in my controller.

According to the HMC833 datasheet, section 1.2.2, I could be able to calibrate VCO and PLL in less than 10µs (with a 50Mhz internal and external SPI clock).

So my question is, are there any other times needed to lock the new frequency ?

Thank you in advance for your answer.
