IDT / ICS LVCMOS/LVTTL ZERO DELAY CLOCK BUFFER

ICS86004 REV B JUNE 21, 2006
ICS86004
15.625MHZ TO 62.5MHZ, 1:4 LVCMOS/LVTTL ZERO DELAY CLOCK BUFFER
APPLICATION INFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS86004 provides sepa-
rate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
DD, VDDA, and VDDO
should be individually connected to the power supply
plane through vias, and bypass capacitors should be
used for each pin. To achieve optimum jitter performance, power
supply isolation is required.
Figure 1 illustrates how
a 10
resistor along with a 10F and a .01F bypass
capacitor should be connected to each V
DDA.

INPUTS:
LVCMOS CONTROL PINS:
All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1k
resistor can be used.
RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
OUTPUTS:
LVCMOS OUTPUT:
All unused LVCMOS output can be left floating. We recommend
that there is no trace attached.
FIGURE 2. ICS86004 SCHEMATIC EXAMPLE
SCHEMATIC EXAMPLE
Figure 2 shows a schematic example of using an ICS86004. It is
recommended to have one decouple capacitor per power pin.
Each decoupling capacitor should be located as close as possible
to the power pin. The low pass filter R7, C11 and C16 for
clean analog supply should also be located as close to the
V
DDA pin as possible.
