With the start of the digital terrestrial broadcasting, we feel the pictures of high-definition quality familiar to ourselves. Together with the advent of the digital terrestrial broadcasting, the FPD is becoming more popular and its price has become reasonable for the consumers. FPD-TVs have beefed up with the additional functions to allow the connection of a variety of external equipment.
Against these backgrounds, solutions to implement multiple inputs and multiple functions in one chip have to be developed for the video switches that input the image of high-defi nition quality.
This IC can support the video signal format of 1080p that is required to input the signal of high-definition image quality. In addition, it has the multiple-function circuit that are composed of 8-bit VCA, LPF switching and FLAG circuits, and this circuit can implement simple development design and the savings in the space for packaging footprint.

(1)	Integrates the 8-bit VCA circuit that can tune variations between tuners.
(2)	Integrates the function to monitor the connection of the external input (FLAG function) to lower the load of the microcomputer.
(3)	Selectable one of three LPF cutoff frequencies so that the selected frequency can be compatible with the resolution and sampling frequency. (fc=6.75MHz, 13.5MHz, or 37.5MHz)
