Ypbpr To Rgb Decoder And 2:1 Video Switch - National SemiconductorThe LMH1251 is a wideband 2:1 Analog Video Switch with
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 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 Stan-
dard Definition Television (SDTV) and High Definition Tele-
vision (HDTV) inputs. It provides bi-level sync, and tri-level
sync separation.
The color space conversion from YPBPR to RGB in the
LMH1251 is realized with a very high precision fully Analog
dematrixer that provides chrominance accuracy that is less
than 2.5% of amplitude & 1.5 of phase error on a vector-
scope. 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. By National Semiconductor Corporation
