PRELIMINARY
CRYSTAL INPUT INTERFACE
The ICS8546-01 has been characterized with 18pF parallel
resonant crystals. The capacitor values shown in Figure 3
Figure 3. CRYSTAL INPUt INTERFACE
below were determined using an 18pF parallel resonant crys-
tal and were chosen to minimize the ppm error.

FIGURE 2. SINGLE ENDED SIGNAL DRIVING DIFFERENTIAL INPUT
Figure 2 shows how the differential input can be wired to accept
single ended levels. The reference voltage V_REF = V
DD/2 is
generated by the bias resistors R1, R2 and C1. This bias circuit
should be located as close as possible to the input pin. The ratio
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS
of R1 and R2 might need to be adjusted to position the V_REF in
the center of the input voltage swing. For example, if the input
clock swing is only 2.5V and V
DD = 3.3V, V_REF should be 1.25V
and R2/R1 = 0.609.
