Datasheet

SNLU100 – April 2012 SERDESUB-16USB User’s Guide 3
System Requirements:
In order to demonstrate, the following are required:
1) Video source with 1.8V or 3.3V LVCMOS parallel interface
2) Microcontroller (MCU) or FPGA with I
2
C interface bus (I
2
C master)
a. slave clock stretching must be supported by the I2C master controller/MCU.
3) External peripheral device that supports I
2
C (slave mode)
4) Power supply for 1.8V (required) and 3.3V (optional)

Figure 1. Typical Application
The diagram above illustrates a typical application of DS90UB901Q/902Q chipset. The
MCU/FPGA can program device registers on the DS90UB901Q, DS90UB902Q, and
remote peripheral device, such as a camera.
