FEATURES
Display
50/60 Hz PIP modes possible
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 needed as external VDRAM
(2 × 1 Mbit or 1 × 2 Mbit)
Four 8-bit Analog-to-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-to-Analog 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.
GENERAL DESCRIPTION
The SAB9077H is a picture-in-picture controller for
multi-standard TV-sets. The circuit contains ADCs,
reduction circuitry, memory control, display control and
DACs.
It 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 base band signals. The conversion
into the digital environment and back to the analog
environment is done on chip. Internal clocks are generated
by two acquisition PLLs and a display PLL.
The two PIP channels and a large external memory offer a
wide range of PIP modes. The emphasis is put on single
PIP, double PIP, split-screen mode and many multi-PIP
modes.
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 available
Border and background brightness adjustable, 30%,
50%, 70% and 100% IRE
Several type of decoder input signals can be set.
