HMC703LP4E reference input slew rate

Hi all,

In the datasheet about reference input,
Slew rate of greater or equal to 0.5 V/ns, it is recommended at low frequencies, a relatively square reference is recommended to keep the input slew rate high.


Is it only rising, falling, or both edges ?

In general,, Falling edge degradates the slew rate.


I think the phase detecter block is trigered rising edge from ref/R and RF/N.
Is it correct ?
Is it difference from ADI PLL and Hittite PLL about edge detect ?

Dose the slew rate of falling edge affects the phase detecter function?


Best regards,
