Multistandard 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 generatesthe 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.
SAB9083
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 horizontal1⁄4 and
vertical1⁄3. In the first two modes, the column(s) can be
placed on the left or right side of the screen.

The internal pixel rate is 28 MHz for the Y, U and V
channels. It is expected that the bandwidth of the input
signals will be limited to 4.5 MHz for the Y input and
1.125 MHz for the U and V inputs. Inset synchronisation is
achieved via the acquisition HSYNC and VSYNC pins of
the main channel. The display is driven by the main
channel clock.

The starting-point of the acquisition can be controlled with
the acquisition fine positioning added to a system
constant. With a nominal input f
signals, 1408 samples (active video) are acquired and
processed by the SAB9083. Here, the nominal input
f
results in a nominal system clock frequency of
HSYNC
1792 × f
(approximately 28 MHz).

I2C-bus description
The I2C-bus provides bidirectional 2-line communication
between different ICs. The SDA line is the serial data line
and the SCL the serial clock line. Both lines must be
connected to a positive supply via a pull-up resistor when
connected to the output stages of a device.
Data transfer may be initiated only when the bus is not
busy. The SAB9083 has the I2C-bus address 2CH. Valid
subaddresses are 00H to 18H, register 15H (except bits 7
and 6) and registers 16H to 18H are reserved for future
extensions.

C-bus control is according to the I2C-bus protocol: first, a
START sequence must be put on the I2C-bus Then, the
I2C-bus address of the circuit must be sent, followed by a
subaddress. After this sequence, the data of the
subaddresses must be sent. An auto-increment function
gives the option of sending data of the incremented
subaddresses until a STOP sequence is sent. Table 1
gives an overview of the I2C-bus addresses. The data bits
that are not used should be set to zero.
