HMC7044 2600MHz output recommendation for AD9208

Dear Sir/Madam,

If I need 2600MHz from HMC7044 CLKOUTx output to connect to AD9208 CLK input is the recommendation AC coupled CML or AC coupled PECL?

The datasheet shows LVPECL having higher bandwidth than CML.

The AD9208 is CLK input has a 300mV to 1800mV pk-pk differential input range and internal termination and self biased.

(1) AC coupled CML

(2) AC coupled PECL

Regards Joe
