Hi Team,

I would like to ask about OUT0_VOD setting.
Programming guide shows the following and there is only 5 settings to adjust and other setting is invalid.

-LMH0318

On the other hand, it seems LMH1218 can be set more detailed setting (more than 5 setting).

-LMH1218

Should we consider adjusting OUT0_VOD of LMH0318 is resticted than that of LMH1218?

Hi Nasser-san,

Reg 0x80[7:4]=0010 is default value for LMH1218 and I believe output voltage is 800mV in default.

On the other hand, Reg 0x80[7:4]=0101 is default value for LMH0318 and it shows output voltage is 800mV in default.

Hi Yaita-San,

LMH1218 default setting is referring to 12G VOD while LMH0318 is referring to 3G VOD. So programming guide for LMH0318 is ok.
