System Overview
(continued)
configuration will then contain four 2-bit numbers indicating the
registers where the gain and offset values are located for a
maximum of four colors on each CFA line. In addition, the CFA
definition register will contain two 2-bit numbers that designate
the number of elements used in each CFA line for the particular
CFA pattern being applied to the system.
Example A contains a CFA pattern that repeats the colors cyan
and magenta on the first line, and repeats the pattern blue,
green, green, blue on the second line. Each 2-bit number in the
CFA line registers refers to a common set of PGA gain and
offset registers for each color. The first line indicates that the
color magenta uses the gain and offset values stored in PGA
gain register 1 (address 1h) and analog offset register 1
(address 5h). Also, the first line indicates that the color cyan
uses the gain and offset values in PGA gain register 2 (address
2h) and analog offset register 2 (address 6h). The second line
indicates gain and offset values for the color blue and the color
green in the same fashion as the first line.
In addition to specifying the gain and offset for each line, it is
also necessary to specify the number of elements contained in
each CFA line’s pixel pattern. The CFA definition register is used
to store this value (number of elements per line). In example A,
the user has stored the 2-bit binary number
01
into the CFA
definition register’s two LSB’s indicating that the pattern in line 0
contains two repeating colors or elements. Also, the 2-bit binary
number
11
has been written into bit 2 and bit 3 of the CFA
definition register indicating that the respective CFA pattern
contains four repeating colors or elements, as the colors blue
and green alternate position in the example pattern.
Once both lines for the pattern have been stored, it is applied
when the beginning of line (BOL) signal is asserted by the user.
One line of the CFA pattern is applied repeatedly until the BOL
signal is reset (at the end of the current line). Once the BOL
signal is set again, the CFA line information is changed from that
defined by the CFA line 0 register to that defined by the CFA line
1 register and the process starts again. For more details of the
timing of the BOL signal, please refer to Figure 6.
1.11 Software Control
There are two software control registers accessible via the serial
interface. The software control registers are divided into
customer (register 0) and advanced (register 1) functions.
Please refer to the register data descriptions for more
information on the software control registers.
1.12 Power Level Control
The LM98503 is equipped with two power trim registers that
may be used to adjust power levels of various circuits internal to
the device. In its default condition, the LM98503 is set for
optimum power and performance, and modifying the values
stored in the power level control registers will affect performance
as a result of the change in power level(s). In applications where
maximum performance is desired, the default values should be
used. Otherwise, power levels may be decreased at the slight
expense of performance. Please refer to the register data
descriptions for more information regarding the power level
control registers.
The ADC coarse and fine bank power adjustment bits are
located in the power level control 2 register, bits 7:4. Altering
these bits may significantly affect performance and power
dissipation. Please see ’DNL vs. Power Control Setting @
18MHz Clock Frequency’ and ’Power Dissipation vs. Power
Control Setting’ on page ’13.
