RZ/A2M SUB Board RTK79210XXB00000BE
2.11
CMOS Camera Interface
RZ/A2M is equipped with an on-chip capture engine unit (CEU) that captures digital image data externally input, and
transfers the data to memory. On RTK79210XXB00000BE, CEU pins of RZ/A2M connect with 26 pin MIL pitch
connector to enable connection with various CMOS cameras.
X6 can be connected to an oscillator to input a sampling clock externally for the CMOS camera.
A pull-up resistor for I2C-bus is already mounted on RTK79210XXB00000BE, therefore it is not needed for the
CMOS camera side.
Figure 2.11.1 shows CMOS camera interface block diagram, and Table 2.11.1 shows a function setting table of DIP
switch SW6-4 for system setting.
