The LMH™1251 is a wideband 2:1 analog video switch
an integrated YPBPR to RGB decoder. The device accepts
one set of YPBPR inputs and one set of RGB/HSYNC/ VSYNC inputs. Based on the input selected, the output be either a decoded TV or buffered PC video signal.
The LMH1251 has a SYNC separator and processor that 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 YPBPR to RGB in LMH1251 is realized with a very high precision fully analog dematrixer that provides chrominance accuracy that is than 2.5% of amplitude & 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.
The LMH1251 is capable of handling SDTV, HDTV, XGA, SXGA, and UXGA video formats, which makes it an ideal solution for enhancing value in applications ranging from LCD monitors, to set-top boxes, to projectors. The LMH1251 is available in a TSSOP-24 package.
