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 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.

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.

FUNCTIONAL DESCRIPTION Acquisition

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

HSYNC

and standard NTSC signals, 1408 samples (active video) are acquired and processed by the SAB9083. Here, the nominal input f

HSYNC

results in a nominal system clock frequency of

1792 × f

HSYNC

(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.
