GLOBAL CONTROL REGISTERS
Register control bits listed in this section affect the whole chip.
POWER-SAVE MODES
Power-Down
PDBP, Address 0x0F [2]
There are two ways to shut down the digital core of the
ADV7183A: a pin (PWRDN) and a bit (PWRDN see below).
The PDBP controls which of the two has the higher priority.
The default is to give the pin (PWRDN) priority. This allows the
user to have the ADV7183A powered down by default.
Table 11. PDBP Function
PDBP
Description
0 (default)
Digital core power controlled by the PWRDN pin
(bit is disregarded).
1
Bit has priority (pin is disregarded).
PWRDN, Address 0x0F [5]
Setting the PWRDN bit switches the ADV7183A into a chip-
wide power-down mode. The power-down stops the clock from
entering the digital section of the chip, thereby freezing its
operation. No I2C bits are lost during power-down. The
PWRDN bit also affects the analog blocks and switches them
into low current modes. The I2C interface itself is unaffected,
and remains operational in power-down mode.
The ADV7183A leaves the power-down state if the PWRDN
bit is set to 0 (via I2C), or if the overall part is reset using the
RESET pin.
PDBP must be set to 1 for the PWRDN bit to power down the
ADV7183A.
Table 12. PWRDN Function

Description
0 (default)
Chip operational.
1
ADV7183A in chip-wide power-down.
ADC Power-Down Control
The ADV7183A contains three 10-bit ADCs (ADC0, ADC1,
and ADC2). If required, it is possible to power down each ADC
individually.
When should the ADCs be powered down?
CVBS mode. ADC1 and ADC2 should be powered down
to save on power consumption.
S-Video mode. ADC2 should be powered down to save on
power consumption.
PWRDN_ADC_0, Address 0x3A [3]
Table 13. PWRDN_ADC_0 Function
PWRDN_ADC_0
Description
0 (default)
ADC normal operation.
1
Power down ADC 0.
PWRDN_ADC_1, Address 0x3A [2]
Table 14. PWRDN_ADC_1 Function
PWRDN_ADC_1
Description
0 (default)
ADC normal operation.
1
Power down ADC 1.
PWRDN_ADC_2, Address 0x3A [1]
Table 15. PWRDN_ADC_2 Function
PWRDN_ADC_2
Description
0 (default)
ADC normal operation.
1
Power down ADC 2.
RESET CONTROL
Chip Reset (RES), Address 0x0F [7]
Setting this bit, equivalent to controlling the RESET pin on the
ADV7183A, issues a full chip reset. All I2C registers get reset to
their default values. (Some register bits do not have a reset value
specified. They keep their last written value. Those bits are
marked as having a reset value of x in the register table.) After
the reset sequence, the part immediately starts to acquire the
incoming video signal.
Notes
After setting the RES bit (or initiating a reset via the pin),
the part returns to the default mode of operation with
respect to its primary mode of operation. All I2C bits are
loaded with their default values, making this bit self-
clearing.
Executing a software reset takes approximately 2 ms.
However, it is recommended to wait 5 ms before any
further I2C writes are performed.
The I2C master controller receives a no acknowledge
condition on the ninth clock cycle when chip reset is
implemented. See the MPU Port Description section.
Table 16. RES Function
RES
Description
0 (default)
Normal operation.
