On page 12 of HMC7044 (Rev. C) (analog.com) the LVPECL common-mode output voltage is specified as VCC-1.3 (typ).
I need to interface to the ZL40217 ClockBuffer ZL40217.book (microchip.com) as per page 8 figure 4 for SYSREF fanout.
On page 17 of ClockBuffer ZL40217.book (microchip.com) the input common mode voltage is 1.1 to 2.0V.
As the HMC7044 common-mode output voltage is (3.3-1.3) 2V (typ) and the ZL40217 common-mode input voltage is 2V (max)
I am concerned that the HMC7044 is at the limit and would be outside for max.
Any comment welcome.
