ICS879893I
LOW SKEW, 1-TO-12 (IDCS)
LVCMOS/LVTTL CLOCK GENERATOR
SCHEMATIC EXAMPLE
Figure 1 shows a schematic example of the ICS879893I. In this
example, the CLK1 input is selected as primary. Both CLK0 and
CLK1 inputs are driven by LVCMOS drivers. For the LVCMOS
outputs, series termination is shown in this example. Additional
LVCMOS termination approached are shown in the LVCMOS
Termination Application Note. In this example, feedback trace
is assumed to be a long trace. The series termination near the
QFB pin is required. If the feedback trace is short, series termi-
nation is not required. If this device is also used as a zero delay
buffer, the application note ZDB Delay Affected by Feedback
Trace provides additional information. For the power pins, it is
recommended to have at least one decoupling capacitor per
power pin. The decoupling capacitors should be physically lo-
cated near the power pins
