Application Notes
- AN-1681 Design Migration from the LM1881 to the LMH1980 (Rev. A)PDF, 79 Kb, Revision: A, File published: May 3, 2013
The LMH1980 is a SD/HD/PC video sync separator intended to replace the LM1881 sync separator inconsumer, security and surveillance, and industrial video applications where high-definition compatibility isneeded. This application report discusses the LMH1980’s advantages over the LM1881 andconsiderations for designing the LMH1980 into current LM1881 sockets.
