LM1270 Hi-Brite 200 MHz I2C Compatible RGB Image Enhancer with Video Auto Sizing May 2003 LM1270 Hi-Brite 200 MHz I2C Compatible RGB Image Enhancer with Video Auto Sizing General Description The LM1270 is a supplementary IC to the low cost chipset (LCCS). It modifies the video stream prior to the LCCS preamplifier. The key function of the LM1270 is image processing for enhancing pictures or motion video. Image enhancement is accomplished by special intermediate frequency boosting. 200 MHz bandwidth assures minimal impact on the video change when adding the LM1270. Other functions of the LM1270 are: 1. Measures the length of the active video and its front porch time with respect to the horizontal flyback and vertical sync for auto alignment information. 2.
