The ICS843-106 has been characterized with 18pF parallel
resonant crystals. The capacitor values, C1 and C2, shown in
Figure 1
below were determined using a 25MHz, 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.
LVCMOS O
UTPUT
:
An unused LVCMOS output should be terminated with 100
Ω
to ground as close as possible to the device.
LVPECL O
UTPUT
All unused LVPECL outputs can be left floating. We recommend
that there is no trace attached. Both sides of the differential
output pair should either be left floating or terminated.
