NOTES
1. VD FALLING EDGE WILL RESET THE
PxGA
GAIN REGISTER STEERING TO “0101” LINE.
2. HD FALLING EDGES WILL ALTERNATE THE
PxGA
GAIN REGISTER STEERING BETWEEN “0101” AND “2323” LINES.
3. FLD STATUS IS IGNORED.

NOTES
1. FLD FALLING EDGE (START OF ODD FIELD) WILL RESET THE
PxGA
GAIN REGISTER STEERING TO “0101” LINE.
2. FLD RISING EDGE (START OF EVEN FIELD) WILL RESET THE
PxGA
GAIN REGISTER STEERING TO “2323” LINE.
3. HD FALLING EDGES WILL RESET THE
PxGA
GAIN REGISTER STEERING TO EITHER “0” (FLD = ODD) OR “2” (FLD = EVEN).

Figure 39b. Mosaic Interlaced Color Steering Mode
example, the Mosaic Separate Steering Mode accommodates the
popular
“
Bayer
”
arrangement of Red, Green, and Blue filters
(see Figure 38a).
The same Bayer pattern can also be interlaced, and the Mosaic
Interlaced Mode should be used with this type of CCD (see
Figure 38b). The color steering performs the proper multiplex-
ing of the R, G, and B gain values (loaded into the
PxGA
gain
registers) and is synchronized by the vertical (VD) and horizon-
tal (HD) sync pulses. The
PxGA
gain for each of the four
channels is variable from
–
2 dB to +10 dB, controlled in 64
steps through the serial interface. The
PxGA
gain curve is
shown in Figure 40.
