Schematic Example
Figure 7 shows a schematic example of the ICS843002I-40
application schematic. In this example, the device is operated at
VCC = 3.3V. The decoupling capacitors should be located as close
as possible to the power pin. The input is driven by a 3.3V LVPECL
driver. The 2-pole filter example is used in this schematic. Please
refer to the ICS843002I-40 datasheet for additional loop filter
recommendations.
Figure 7. ICS843002I-40 Schematic Example
Loss of Reference Indicator (LOR0 and LOR1) Output Pins
The LOR0 and LOR1 pins are controlled by the internal clock
activity monitor circuits. The clock activity monitor circuits are
clocked by the VCXO PLL phase detector feedback clock. The
LOR output is asserted high if there are three consecutive
feedback clock edges without any reference clock edges (in both
cases, either a negative or positive transition is counted as an
“edge”). The LOR output will otherwise be low. In a phase detector
observation interval, the activity monitor does not flag excessive
reference transitions as an error. The monitor only distinguishes
between transitions occurring and no transitions occurring.
