Description
General part information
LMH1251 Series
The LMH1251 is a wideband 2:1 analog video switch with an integrated YPBPRto RGBHV converter. The device accepts one set of YPBPRinputs and one set of RGB/HSYNC/VSYNC inputs. Based on the input selected, the output will be either a decoded TV or buffered PC video signal.
The LMH1251 has a SYNC separator and processor that is capable of extracting sync timing information from both Standard Definition Television (SDTV) and High Definition Television (HDTV) inputs. It provides bi-level sync, and tri-level sync separation.
The color space conversion from YPBPRto RGB in the LMH1251 is realized with a very high precision fully analog dematrixer which provides superior chroma accuracy that is less than 2.5% of amplitude and 1.5° of phase error on a vectorscope. It is equipped with a smart video detection circuit which automatically senses SDTV and HDTV video formats and applies the appropriate color space conversion.
