Typical Connection and Test Equipment

The following is a list of typical test equipment that may be used to generate signals for the

Serializer inputs:

1) Digital Video Source – for generation of specific display timing such as a Graphics

Controller or CMOS imager with digital video signals (1.8V/3.3V LVCMOS).

2) Any other signal generator / video source that generates the correct input levels.

The following is a list of typical test equipment that may be used to monitor the output

signals from the Deserializer:

1) A display module (such as an LCD)

2) Controller or capture card which supports digital video signals (1.8V/3.3V

LVCMOS).

3) Video capture card

4) Microcontroller or FPGA with an I

C interface

5) Optional – Logic Analyzer or Oscilloscope

6) Any SCOPE with a bandwidth of at least 50MHz for 1.8V/3.3V LVCMOS and/or

1.5GHz for observing differential signals.

Figure 4 below illustrates an application using a MCU/FPGA controller connected to

DS90UB903Q with I

C bus and a display module connected to DS90UB904Q with I

bus. Both MCU/FPGA controller video and control information are transferred on the same

serial video link.
