Wayne,

The LMH1982 and LMH1983 are commonly used for GENLOCK applications.
Thanks,

Kadeem

Kadeem：

Thanks for the reply， I know the LMH1981 and LMH1983 can implement the Genlock IN ， but I wonder how the Genlock loopout scheme works

Hi Wayne,

Input to the LMH1981 is an analog video signal, so your one-in two-out block should be a video buffer.

Please reach out to the amplifier team for recommendation.

Hi Wayne,

LMH1981 accepts analog video but not SDI signal, LMH0395 is not appropriate here. Please check with the Amplifier team for analog video fanout solution.
