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.
