IDT / ICS 3.3V LVPECL FREQUENCY SYNTHESIZER

ICS8430DY-111 REV. F JANUARY 29, 2007
ICS8430-111
700MHZ, LOW JITTER, DIFFERENTIAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER
PRELIMINARY
APPLICATION INFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS8430-111 provides
separate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
CC, VCCA, and VCCO
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 2 illustrates how a 10
Ω
resistor along with a 10
μF and a .01μF bypass capacitor
should be connected to each V
CCA pin. The 10Ω resistor can
also be replaced by a ferrite bead.

INPUTS:
TEST_CLK INPUT:
For applications not requiring the use of the test clock, it can be
left floating. Though not required, but for additional protection, a
1k
Ω resistor can be tied from the TEST_CLK to ground.
CLK/nCLK INPUT:
For applications not requiring the use of the differential input,
both CLK and nCLK can be left floating. Though not required, but
for additional protection, a 1k
Ω resistor can be tied from CLK to
ground.
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
Ω resistor can be used.
RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
OUTPUTS:
LVPECL OUTPUT
All unused LVPECL outputs can be left floating. We recommend
that there is no trace attached. Both sides of the differential output
pair should either be left floating or terminated.
