Product Summary
The tda9340ps/n3/a/1923 is an IC-bus controlled TV display processor. The tda9340ps/n3/a/1923 contains the following functions: RGB control processor with Y, U and V inputs; Programmable deflection processor with internal clock generation, which generates the drive signals for the horizontal, East-West (E-W) and vertical deflection; The circuit can be used in both single scan (50 or 60 Hz) and double scan (100 or 120 Hz) applications. The tda9340ps/n3/a/1923 has a multi-sync function for the horizontal PLL, with a frequency range from 30 to 50 kHz (2fH mode) or 15 to 25 kHz (1fH mode), so that the ICs can also be used to display SVGA signals.
