I am using HMC7044 evaluation card.
I would like to know what is the range for SPI of HMC as it is not mentioned in data sheet?
Could you please let me know if it supports 2.5V for the SPI?
All SPI signal levels are given in Table-3 of datasheet. As long as you fit these specs, 2.5V for SPI can be safely used.
Yes I found it there.

Hi, Kazim! According to the table 3 Logic 1 level of bidirectional outputs is 1.6V min. 1.9V typ. and 2.2V max.
Is the logic 1 level equal to the output voltage level on this pins? i'm a bit confused about this. HMC7044 is powered with 3.3V and how output voltage can be less then 3.3V?
Yes, these are output voltage levels for these pins. External 3.3V input is regulated to a variety of different voltage levels for different internal blocks. The SPI block is not powered-up by 3.3V. As a result of this structure output voltages lower than 3.3V is generated.
