ICS527-01
Using the equation for selecting dividers gives:
If FDW = 0, then RDW = 8. This gives the required divide-by-5 function. Setting pin DIV2 = 1 gives both a
25 MHz and a 50 MHz output from the ICS527-01. The FBIN pin is connected to the QA7 output of the
MK74CB218. This aligns all the outputs of the MK74CB218 with the 25 MHz input since the ICS527-01
aligns rising edges on the ICLK and FBIN pins. The propagation delay of the buffer is compensated by the
PLL.
In this example, series termination resistors have been omitted for clarity but should be used on all clock
outputs.
PCB Layout Recommendations
For optimum device performance and lowest output
phase noise, the following guidelines should be
observed.
1) Each 0.01F decoupling capacitor should be
mounted on the component side of the board as close
to the VDD pin as possible. No via’s should be used
between decoupling capacitor and VDD pin. The PCB
trace to VDD pin should be kept as short as possible,
as should the PCB trace to the ground via.
2) To minimize EMI the 33
series termination resistor,
if needed, should be placed close to the clock outputs.
3) An optimum layout is one with all components on the
same side of the board, minimizing vias through other
signal layers. Other signal traces should be routed
away from the ICS527-01. This includes signal traces
just underneath the device, or on layers adjacent to the
ground plane layer used by the device.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS527-01. These ratings,
which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of
the device at these or any other conditions above those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can
affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.
