CCD Signal Processor Block Serial Interface Control
The CXD3410GA's CCD signal processor block basically loads the CCD signal processor block serial interface
data sent in the following format at the rising edge of SEN2, and the setting values are then reflected to the
operation 6 ADCLKI clocks after that.
CCD signal processor block serial interface control requires clock input to ADCLKI in order to load and reflect
the serial interface data to operation, so this should normally be performed when the timing generator block is
in the normal operation mode.
There are four categories of CCD signal processor block serial interface data: standby control data, PGA gain
setting data, OB clamp level setting data, and input pulse polarity setting data.
Note that when data from multiple categories is loaded consecutively, the data for the category loaded last is
valid and data from other categories is lost. When transferring data from multiple categories, raise SEN2 for
each category and wait until the setting value 6 ADCKLI clocks after that has been reflected to operation, then
transmit the next category.
The detail of each data are described below.
