INTEGRATED CIRCUITS DATA SHEET SAB9082 NTSC Picture-In-Picture (PIP) controller Preliminary specification Supersedes data of 1999 Feb 18 File under Integrated Circuits, IC02 1999 Nov 12 Philips Semiconductors Preliminary specification NTSC Picture-In-Picture (PIP) controller FEATURES Double window Picture-in-Picture (PIP) in interlaced or non-interlaced mode at 8-bit resolution Internal 1-Mbit DRAM Three 8-bit Analog-to-Digital Converters (ADCs) (7-bit performance) with clamp circuit for each acquisition channel One PLL which generates the line-locked clocks for the subchannel One PLL which generates the line-locked clocks for the main and display channels Three 8-bit Digital-to-Analog Converters (DACs) Linear zoom in both horizontal and vertical directions for the subchannel Linear zoom in horizontal direction for the main channel Three multistandard PIP modes are available. GENERAL DESCRIPTION The SAB9082 is an NTSC PIP controller which can be used in double window applications. The SAB9082 inserts one or two live video signals with reduced size into another live video signal. The incoming video signals are expected to be analog baseband signals. SAB9082 The conversion to the digital environment is done on chip with ADCs. Processing and storage of the video data is done entirely in the digital domain. The conversion back to the analog domain is done by means of DACs. Internal clocks are generated by PLLs which lock on to the applied horizontal and ver...
