GENERAL DESCRIPTION

The SAB9079HS is a PIP controller for a multistandard application environment in combination with a multistandard decoder such as for example TDA8310, TDA9143 or TDA9321H.

FEATURES

? Suitable for single PIP, double window and multi PIP applications

? Data formats 4 : 1 : 1 (all modes) and 4 : 2 : 2 (most modes)

? Sample rate of 14 MHz, 720 Y*-pixels/line

? Horizontal reduction factors 1?1 3?4, 2?3, 1?2, 1?3, 1?4 and 1?6

? Vertical reduction factors 1?1, 1?2, 1?3 and 1?4

? PIP OSD for the sub channels displayed

? Detection of PAL/NTSC with overrule bit

? CTE/LTE like circuits in display part

? Replay with definable auto increment, picture sample rate and picture number auto wrap

? Programmable Y*UV to RGB conversion matrix with independent coefficients for NTSC and PAL sources

? Display clock and synchronisation are derived from the main PLL

? Three 8-bit Digital-to-Analog Converters (DACs)

? Three 8-bit Analog-to-Digital Converters (ADCs) (7-bit performance) with clamp circuit for each acquisition channel

? Main and sub can write to the same VDRAM address spaces under certain conditions; the reduction factors should be the same

? Y* and UV pedestals on the acquisition sides

? Independent vertical filtering with 1 : 1 for UV and Y* at the display part.
