EFERENCE

Chapter 4 describes the hardware components and principal hardware
subsystems of the RCM5400W. Appendix A, “RCM5400W Specifica-
tions,” provides complete physical and electrical specifications.

Figure 6 shows the Rabbit-based subsystems designed into the RCM5400W.

Figure 6. RCM5400W Subsystems

The 73.73 MHz frequency shown for the RCM5400W is generated using a 36.864 MHz
crystal with the Rabbit 5000 clock doubler enabled.
