... The effective fanout can be increased from utilizing the ability of the outputs to drive two series terminated lines. The ICS83905 is characterized at full 3.3V, 2.5V, and 1.8V, mixed 3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply mode. Guaranteed output and part-to-part skew char- acteristics along with the 1.8V output capabilities makes the ICS83905 ideal for high performance, single ended applica- tions that also require a limited output voltage ...

... I RYSTAL NPUT NTERFACE Figure 2 shows an example of ICS83905 crystal interface with a parallel resonant crystal. The frequency accuracy can be fine tuned by adjusting the C1 and C2 values. For a parallel crystal with loading capacitance CL = 18pF, we suggest C1 = 15pF and C2 = 15pF to start with. These values may be slightly fine tuned ...

... LOW SKEW, 1:6 CRYSTAL-TO-LVCMOS/LVTTL FANOUT BUFFER L G AYOUT UIDELINE Figure 5 shows an example of ICS83905 application schematic. In this example, the device is operated at V 3.3V. The decoupling capacitors should be located as close as possible to the power pins. The input is driven by an 18pF load resonant quartz crystal. The tuning capacitors (C1, C2) are fairly ...
