LMK03328 Output Power

I have a customer asking the following questions:

My question is what kind of power you can get at around 900MHz single ended at each of the 16 outputs?

I am trying to get an RF oscillator output in the range of 100MHz to 1GHz approximately 5dBm.

Can the outputs deliver the power that the customer has requesting when operating in this fashion?

Thanks for your help with this!

Has anyone had a chance to look at the request above?

Can you give a time frame as to when you might be able to provide the information?

Thanks for your help with this!

It's about 0 dBm for LVPECL at 900 MHz. See Figure 20 and divide by 2 to get single ended voltage swing.

A low loss balun transformer can be used to convert the differential output to single ended, and get close to the +5 dBm output power they're seeking.

Alan,

Thanks for your response!

I will let you know if the customer has any further questions.
