data byte to be read will be from the register address
location set by the previous transaction and not 0x00,
and subsequent reads will autoincrement the address
pointer until the next STOP condition. Attempting to
read from register addresses higher than 0x01 results
in repeated reads from a dummy register containing
0xFF data. The master acknowledges receipt of each
read byte during the acknowledge clock pulse. The
master must acknowledge all correctly received bytes
except the last byte. The final byte must be followed by
a not acknowledge from the master and then a STOP
condition. Figures 10 and 11 illustrate the frame format
for reading data from the MAX9507.
Applications Information
Power Consumption
The quiescent power consumption and average power
consumption of the MAX9507 is remarkably low
because of 1.8V operation and DirectDrive technology.
Quiescent power consumption is defined when the
MAX9507 is operating without load. In this case, the
MAX9507 consumes about 5.8mW. Average power
consumption, which is defined when the MAX9507 dri-
ves a 150
Ω
load to ground with a 50% flat field, is
about 11.7mW. Table 5 shows the power consumption
with different video signals. The supply voltage is 1.8V
and OUT drives a 150
Ω
load to ground.
Notice that the two extremes in power consumption occur
with a video signal that is all black and a video signal that
is all white. The power consumption with 75% color bars
and 50% flat field lies in between the extremes.
