Preliminary specification
Multistandard Picture-In-Picture (PIP)
controller
SAB9083
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 SAB9083 is a multistandard PIP controller which can
be used in double window applications. The SAB9083
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.
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 vertical syncs.
The main input channel is compressed horizontally by a
factor of two and directly fed to the output. After
compression, a horizontal expansion of two is possible for
the main channel.
The subchannel is also compressed horizontally by a
factor of two but stored in memory before it is fed to the
outputs.
The SAB9083 can also create three multistandard PIP
modes, one with three PIPs placed in a column (MP3) and
two with two columns of three PIPs (MP6, MP6S).
The reduction factors of these PIPs are horizontal
1
4
and
vertical
1
3
. In the first two modes, the column(s) can be
placed on the left or right side of the screen.
