LVCMOS Outputs
All unused LVCMOS output can be left floating. There should be no
trace attached.
Crystal Input Interface
The 83905-01 has been characterized with 18pF parallel resonant
crystals. The capacitor values, C1 and C2, shown in Figure 2 below
were determined using an 18pF parallel resonant crystal and were
chosen to minimize the ppm error. The optimum C1 and C2 values
can be slightly adjusted for different board layouts.
