LMH1251 YP P to RGBHV Converter and 2:1 Video Switch

B R

Check for Samples: LMH1251

FEATURES

DESCRIPTION

The LMH1251 is a wideband 2:1 analog video switch

with an integrated YP_BP_Rto RGBHV converter. The

device accepts one set of YP_BP_Rinputs 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.

•

YP_BP_Rto RGBHV Conversion

•

YP_BP_RPath: 70 MHz, −3 dB, 700 mV_PP

Bandwidth

•

RGB Path: 400 MHz, −3 dB, 700 mV_PP

Bandwidth

Supports PC Video Display Resolutions up to

UXGA (1600 x 1200 @ 75 Hz)

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.

Supports 480i, 480p, 576i, 576p, 720p, 1080i,

and 1080p

•

Smart Video Format Detection for SD and HD

Power Save Mode

The color space conversion from YP_BP_Rto 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.

APPLICATIONS

•

TFT LCD Monitor

CRT Monitor

Set-Top Box

Display Projector

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 part of the LMH™ high

speed amplifier family, and is offered in a 24-pin

TSSOP package.
