Overview
INTEGRATED CIRCUITS DATA SHEET SAB9076H Picture-In-Picture (PIP) controller Preliminary specification File under Integrated Circuits, IC02 1996 Aug 13 Philips Semiconductors Preliminary specification Picture-In-Picture (PIP) controller FEATURES Display • Twin PIP in interlaced mode at 8-bit resolution • Sub-title mode features built in • Large display fine positioning area, both channels independent • Only 2 Mbit required as external VDRAM (2 × 1 Mbit or 1 × 2 Mbit) • Four 8-bit Analogue Digital Converters (ADCs; > 7-bit performance) with clamp circuit • Most PIP modes handle interlaced pictures without joint line error • Two PLLs which generate the line-locked clocks for the acquisition channels • Display PLL to generate line-locked clock for the display • Three 8-bit Digital Analogue Converters (DACs) • 4 : 1 : 1 data format • Data reduction factors 1 to 1, 1 to 2, 1 to 3 and 1 to 4, horizontal and vertical independent.
I2C-bus programmable • Single and double PIP modes can be set • Full field still mode available • Several aspect ratios can be handled • Reduction factors can be set freely • Selection of vertical filtering type • Freeze of live pictures • Fine tuned display position, H (8-bit), V (8-bit), both channels independent • Fine tuned acquisition area, H (4-bit), V (8-bit), both channels independent • Eight main borders, sub-borders and background colours selectable • Border and background brightness adjustable, 30%, 50%, 70% and 100% IRE • Several type of decoder input signals can be set.
SAB9076H GENERAL DESCRIPTION The SAB9076H is a picture-in-picture controller for NTSC TV-sets.
The circuit contains ADCs, reduction circuitry, memory control, display control and DACs.
The device inserts one or two live video signals with original or reduced sizes into a live video signal.
All video signals are expected to be analog baseband signals.
The conversion into the digital environment and back to the analog environment is carried out on chip.
