Part Number: LMH1218
Other Parts Discussed in Thread: LMH1219

Hi, all

I am using LMH1218 for SDI interface, and I would like to know how long SDI coax cable can LMH1218 drive, like 80m, 100m etc. if impedance matching is good condition?

Hi Yamada-San,

12G SDI coax cable reach mainly depends on the receiving cable equalizer device such as LMH1219. A combination of LMH1218 and LMH1219 can achieve 75m B1694A or 100m Canare 5.5CUHD cable length.

Hi Nasser san

This is general question about receiving cable equalizer. Almost all SDI receivers are installing equalizer device such as LMH1219?
