LMK04828: DC coupling for SYSREF

Part Number: LMK04828


We are porting a design from HMC7044 to LMK04828 and the SYSREF outputs are DC coupled LVPECL with a resistor divider to bring  the swing into range for LVDS receivers, as shown below.image.png

The DC coupling is used to avoid the SYSREF floating on the receiver side when being used in pulsed mode. What does TI recommend for LMK04828?
