HMC-747

Hello,

 

I have a question regarding DC Coupling LVDS to CML, I have a non-DC balanced LVDS signal, with a low duty cycle pulse that I need to

interface with the HMC747 flip flop (a CML part) .  The signal is currently driven by an Aeroflex/Cobham UT54LVDS031LVE LVDS driver. Can I directly connect this LVDS driver to the HMC747? The HMC747 will provide the required 100 ohms termination to the LVDS driver, correct? Is this direct connection approach acceptable/safe? If not, can you recommend any alternative termination schemes?  Thanks.

 

Best Regards.
