Main-Clock - Fujitsu F2MC-16LX FAMILY Installation Manual

The Figure 2-2 shows the schematic of the Clock-Supply circuit. The right setting has to be
done by Dip-Switch SW3 (FC SEL) and S2 (SUB XTAL).

2.1.2 Main-Clock

It is recommended to install a crystal and two capacitors (about 15 pF) directly to the
Adapter Board. See Figure 2-1: Main-Clock
To supply the main clock from the user system, add an oscillator to the user system and
have the main clock supplied using a CMOS buffer.
Please refer to the graphic above and to the Figure 2-1 how to enable the Main-Clock.
