MCM
connector for testing
A
connector will be needed for testing purposes of the MCM (Multi
Chip Module).
There are 16 data lines
and 3 control lines and one clock line. Clock and data lines should
work
up to 120 MHz. Therefore short
cable and board trace length are essential. Hence proper grounding
is essentially, too.
The
following pinout is suggested for MCM test connector :
