AN5095K
Single chip IC with I2C bus interface for PAL/NTSC color TV system
s Overview
The AN5095K is an IC in which PAL/NTSC color television signal processing circuits are integrated into a single chip. Also, since the I2C bus interface is built in the IC, the rationalization of set production line can be realized.
