140 MHz video controller with I²C-bus
12.1 Test boards
For high frequency measurements a special test
application and printed-circuit board with only a few
external components is built. It utilizes the internal positive
feedback of the output signals during output clamping with
control bit FPOL = 1. Figure 16 shows the test application
circuit and Figs 17 and 18 show the layout and mounting
of the double-sided printed-circuit board. Most
components are of SMD type. Short HF loops and
minimum crosstalk between the channels and between
signal inputs and outputs are achieved by properly shaped
ground areas.
