LMH1218: Power consumption

user4779049

Part Number: LMH1218

Hi Team,

Please advise me on a question bellow.

Q1 The LM1218 datasheet stats the typical power consumption as 300 mW
(Locked 75 Ω OUT0 only (800 mVpp), EOM powered down).
Does is value measured with two set of 75 ohm load resisters are connected to
the OUT0+ and OUT0- respectively?

Hi Mita-san,

This specification is measured with a 75-ohm termination at both outputs. Since the cable driver is designed for use as a single-ended output for 75-ohm coaxial cable, this measurement was taken with OUT0+ connected to a 75-ohm termination at the BNC, while OUT0- is terminated with 75-ohm resistor to GND.

Thanks,

Michael
