With regards to Multiphase LTM8051

Hi , 

I would like to know if i can use LTM8051 in the following configuration .

I would like to use every channel with clock shifted by 90 Degree. 

If so please let me know how to use SYNC and CLKOUT pins on LTM8051 .

From data sheet we see when SYNC is powered by 2.4 - 4.2 V then it will working spread spectrum and clock will shifted with 90 Degree from channel 1/2 .

[the CLKOUT14/23 pin provides a waveform about 90 degrees out-of-phase with Channel 1/2 respectively] what does this mean .

Thanking you 

With best regards
