CDCLVP111-SP: Power dissipation at 100MHz x 6

Kazuhiko Hirano

Part Number: CDCLVP111-SP

Hello,

My customer plans to use CDCLVP111-SP to distribute 6x 100MHz differential LVPECL output. In this case how much the device internal power dissipation would be at maximum?

Kazuhiko,

Sorry for the delay. I have been unable to find any data on this, but I am going to see if we have a device in the lab that I can just run on the bench.

Kazuhiko,

I used the EVM and terminated 6 outputs with 50 ohm terminations and had a 100MHz input signal. The EVM has two power supplies which I set to nominal voltage values of 3.3V and 2V respectively. The 3.3V supply drew .049A and the 2V supply drew .141A. This was all done at room temperature.

I hope this helps.

Regards,

Will
