Bi-CMOS IC
LV762XXX
Series
Overview
For NTSC/PAL/SECAM Color TVs
Built-in CTV Microcontroller
Video and Sound Processing ICs
(VIF/SIF/Y/C/Deflection/CbCr IN)
The LV762XXX series is a single-chip video and sound processor IC with a built-in microcontroller that supports all of the
NTSC, PAL and SECAM broadcasting systems. The IC provides fully integrated solution to rationalize the design of color
TV sets, increase productivity, and reduce total costs.
