Part Number: LMH1219
We're using the LMH1219 low power 12G UHD adaptive cable equalizer with integrated reclocker in our video equipment, running both 3G-SDI and 12G-SDI signals.
We're seeing video drop out over time, and on loss and reconnection of video. When this happens, Register 0x7 on the CableEQ/DivEQ page changes from 0x24 to 0xFF. This is the specific register change that correlates with video stopping. We're also seeing other registers change unexpectedly, but 0x7 is the one that breaks video.
This is occurring on some units but not others, all from the same manufacturing batch.
Can you tell us what Register 0x7 controls and what conditions would cause it to transition from 0x24 to 0xFF?
