Preliminary specification
Multistandard Picture-In-Picture (PIP)
controller
SAB9081
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 SAB9081. Here, the nominal input
f
HSYNC
results in a nominal system clock frequency of
1792
×
f
HSYNC
(approximately 28 MHz).

C-bus description
The I
2
C-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 SAB9081 has the I
2
C-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.
I
2
C-bus control is according to the I
2
C-bus protocol: first, a
START sequence must be put on the I
2
C-bus. Then, the
I
2
C-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 I
2
C-bus addresses. The data bits
that are not used should be set to zero.
