Other Parts Discussed in Thread: DS90UB913A-Q1

Hello,
 
I have some question about DS90UB913,4 A-Q1.
 
(1) Reducing method of Power Comsumption
DS90UB913A-Q1 supply current is 90mA at worst case.
Our customer said that this supply current is high...
Could you please let me know the method of reducing power consumption if there is?
 
(2) Maximum Power of  Power Over Coax
Since DS90UB913A-Q1 can be used coaxial cable , we can use Power Over Coax.
Could you please let me know the maximum transmission current and voltage and power ?
 
Best Regards,
Ryuji Asaka

    There is no easy way to reduce the power dissipation of the DS90UB913A while operating, but it does have the ability to be powered down while not in operation/

    We are in the process of producing an applications note which discusses how to use power over coax for the DS90UB913A.   If you send me an e-mail at mark.sauerwald@yahoo.com I will reply with a draft of the app. note.   There have been many successful designs implemented where power is sent over the coax cable to power a camera or similar circuit at the far end.
