GENERAL DESCRIPTION
The ADG799A/ADG799G are monolithic CMOS devices
comprising three 2 × 2 crosspoint switches controllable via a
standard I2C serial interface. The CMOS process provides
ultralow power dissipation, yet offers high switching speed and
low on resistance.
The on resistance profile is very flat over the full analog input
range and wide bandwidth ensures excellent linearity and low
distortion. These features, combined with a wide input signal
range, make the ADG799A/ADG799G the ideal switching
solution for a wide range of TV applications including RGB and
YPbPr video switches for picture-in picture applications.
The switches conduct equally well in both directions when on.
In the off condition, signal levels up to the supplies are blocked.
The ADG799A/ADG799G switches exhibit break-before-make
switching action. The ADG799G has two general-purpose logic
output pins controlled by the I2C interface that can also be used
to control other non-I2C-compatible devices such as video filters.
The integrated I2C interface provides a large degree of flexibility
in the system design. It has three user-adjustable I2C address
pins that allow up to eight devices on the same bus. This allows
the user to expand the capability of the device by increasing the
size of the switching array.
The ADG799A/ADG799G operate from single 3 V or 5 V supply
voltages and are available in a compact, 4 mm × 4 mm body,
24-lead, Pb-free LFCSP.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

ADG799A/ADG799G
THEORY OF OPERATION
The ADG799A/ADG799G are monolithic CMOS device
comprising three 2 × 2 crosspoint switches controllable via a
standard I2C serial interface. The CMOS process provides
ultralow power dissipation, yet offers high switching speed and
low on resistance.
The on resistance profile is very flat over the full analog input
range, and wide bandwidth ensures excellent linearity and low
distortion. These features, combined with a wide input signal
range, make the ADG799A/ADG799G an ideal switching
solution for a wide range of TV applications.
3.
Data transmits over the serial bus in sequences of nine
clock pulses (eight data bits followed by an acknowledge
bit). The transitions on the SDA line must occur during the
low period of the clock signal, SCL, and remain stable
during the high period of SCL. Otherwise, a low-to-high
transition when the clock signal is high can be interpreted
as a stop event that ends the communication between the
master and the addressed slave device.
4.
After transferring all data bytes, the master establishes a
stop condition, defined as a low-to-high transition on the
SDA line while SCL is high. In write mode, the master pulls
the SDA line high during the 10th clock pulse to establish a
stop condition. In read mode, the master issues a no
acknowledge for the ninth clock pulse (the SDA line
remains high). The master then brings the SDA line low
before the 10th clock pulse, and then high during the 10th
clock pulse to establish a stop condition.
The switches conduct equally well in both directions when on.
In the off condition, signal levels up to the supplies are blocked.
The integrated serial I2C interface controls the operation of the
crosspoint switches (ADG799A/ADG799G) and generalpurpose logic pins (ADG799G only).
The ADG799A/ADG799G have many attractive features, such as
the ability to individually control each switch, the option of reading
back the status of any switch. The ADG799G has two generalpurpose logic output pins controllable through the I2C interface.
The following sections describe these features in more detail.
I2C SERIAL INTERFACE
The ADG799A/ADG799G are controlled via an I2C-compatible
serial bus interface (refer to the I2C-Bus Specification available
from Philips Semiconductor) that allows the part to operate as a
slave device (no clock is generated by the ADG799A/ADG799G).
The communication protocol between the I2C master and the
device operates as follows:
1.
2.
The master initiates data transfer by establishing a start
condition (defined as a high-to-low transition on the SDA
line while SCL is high). This indicates that an address/data
stream follows. All slave devices connected to the bus
respond to the start condition and shift in the next eight
bits, consisting of a seven bit address (MSB first) plus an
R/W bit. This bit determines the direction of the data flow
during the communication between the master and the
addressed slave device.
The slave device whose address corresponds to the
transmitted address responds by pulling the SDA line
low during the ninth clock pulse (this is known as the
acknowledge bit).
At this stage, all other devices on the bus remain idle while
the selected device waits for data to be written to, or read
from, its serial register. If the R/W bit is set high, the
master reads from the slave device. However, if the R/W bit
is set low, the master writes to the slave device.
I2C ADDRESS
The ADG799A/ADG799G each have a seven-bit I2C address.
The four most significant bits are internally hardwired while the
last three bits (A0, A1, and A2) are user-adjustable. This allows
the user to connect up to eight ADG799A/ADG799Gs to the same
bus. The I2C bit map shows the configuration of the seven-bit
address.

WRITE OPERATION
When writing to the ADG799A/ADG799G, the user must
begin with an address byte and R/W bit. Next, the switch
acknowledges that it is prepared to receive data by pulling SDA
low. Data is loaded into the device as a 16-bit word under the
control of a serial clock input, SCL. Figure 31 illustrates the entire
write sequence for the ADG799A/ADG799G. The first data
byte (AX7 to AX0) controls the status of the crosspoint switches
and the GPO pins, while the LDSW and RESETB bits from the
second byte controls the operation mode of the device. Table 6
shows a list of all commands supported by the
ADG799A/ADG799G with the corresponding byte that needs
to be loaded during a write operation.
To achieve the desired configuration, one or more commands
can be loaded into the device. Any combination of the commands
listed in Table 6 can be used with the following restrictions:
•
The commands referring to more than one switch
overwrite any previous command.
•
When a sequence of successive commands affect the same
element (that is, the switch or GPO pin), only the last
command is executed.

ADG799A/ADG799G
LDSW BIT
POWER ON/SOFTWARE RESET
The LDSW bit allows the user to control the way the device
executes the commands loaded during the write operations.
The ADG799A/ADG799G execute all the commands loaded
between two successive write operations that have set the
LDSW bit high.
The ADG799A/ADG799G has a software reset function
implemented by the RESETB bit from the second data byte
written to the device. For normal operation of the crosspoint
switch and GPO pins, this bit should be set high. When RESETB =
low or after power-up, the switches from all crosspoint switch
pins are turned off (open) and the GPO pins are set low.
Setting the LDSW high for every write cycle ensures that the
device executes the command immediately after the LDSW bit
is loaded into the device. This setting can be used when the
desired configuration can be achieved by sending a single
command or when the switches and/or GPO pins are not
required to be updated at the same time. When the desired
configuration requires multiple commands with simultaneous
updates, the LDSW bit should be set low while loading the
commands except for the last one when the LDSW bit should
be set high. Once the last command with LDSW = high is
loaded, the device simultaneously executes all commands
received since the last update.
READ OPERATION
When reading data back from the ADG799A/ADG799G, the
user must begin with an address byte and R/W bit. The switch
then acknowledges that it is prepared to transmit data by
pulling SDA low. Following this acknowledgement, the
ADG799A/ADG799G transmit two bytes on the next clock
edges. These bytes contain the status of the switches, and each
byte is followed by an acknowledge bit. A logic high bit
represents a switch in the on (close) state while a low represents
a switch in the off (open) state. For the GPO pins (ADG799G
only), the bit represents the logic value of the pin. Figure 32
illustrates the entire read sequence.
The bit maps accompanying Figure 32 show the relationship
between the elements of the ADG799A and ADG799G (that is,
the switches and GPO pins) and the bits that represent their
status after a completed read operation.

EVALUATION BOARD
The EVAL-ADG799GEB allows designers to evaluate the high
performance of the device with minimum effort.
The evaluation kit includes a printed circuit board populated
with the ADG799G. The evaluation board can be used to
evaluate the performance of both the ADG799A and
ADG799G. It interfaces to the USB port of a PC, or it can be
used as a standalone evaluation board. Software is available with
the evaluation board that allows the user to easily program the
ADG799G through the USB port. Schematics of the evaluation
board are shown in Figure 33 and Figure 34. The software runs
on any PC with Microsoft® Windows® 2000 or Windows XP and
a minimum screen resolution of 1200 × 768.
USING THE ADG799G EVALUATION BOARD
The ADG799G evaluation kit is a test system designed
to simplify the evaluation of the device. Each input/output
of the part comes with a socket specifically chosen for easy
audio/video evaluation. A data sheet is also available with the
evaluation board offering full information on how to operate
the evaluation board.
