ICS840014I
FEMTOCLOCKS™ C RYSTAL-TO-
LVCMOS/LVTTL FREQUENCY SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS840014I is a 4 output LVCMOS/LVTTL
Synthesizer optimized to generate Fibre Channel
reference clock frequencies and is a member of
the HiPerClocksTM family of high performance
clock solutions from ICS. This device uses a
26.5625MHz, 18pF parallel resonant crystal to synthesize
106.25MHz. Using FemtoClock’sTM ultra-low phase noise VCO
technology, the ICS840014I can achieve 1ps or lower typical
random rms phase jitter, easily meeting Fibre Channel jitter
requirements. The ICS840014I is packaged in a small 20-pin
TSSOP package.

APPLICATION INFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS840014I provides
separate power supplies to isolate any high switching
noise from the outputs to the internal PLL. VDD, 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 10Ω resistor along with a 10µF and a .01µF bypass
capacitor should be connected to each VDDA.

LAYOUT GUIDELINE
Figure 3
shows a schematic example of the ICS840014I. An
example of LVCMOS termination is shown in this schematic.
Additional LVCMOS termination approaches are shown in
the LVCMOS Termination Application Note. In this example,
an 18pF parallel resonant 26.5625MHz crystal is used. The
FIGURE 3. ICS840014I SCHEMATIC EXAMPLE
C1=22pF and C2=22pF are recommended for frequency ac-
curacy. For different board layout, the C1 and C2 may be
slightly adjusted for optimizing frequency accuracy. 1KΩ
pullup or pulldown resistors can be used for the logic control
input pins.
