GENERAL DESCRIPTION
FEATURES
The ICS86953I-147 is a low voltage, low skew • 9 single ended LVCMOS/LVTTL outputs;
ICS
1-to-9 Differential-to-LVCMOS/LVTTL Clock
Generator and a member of the HiPerClockS™
family of High Performance Clock Solutions from
ICS.The PCLK, nPCLK pair can accept most stan-
(8) clocks, (1) feedback
HiPerClockS™
• PCLK, nPCLK pair can accept the following differential
input levels: LVPECL, CML, SSTL
dard differential input levels.With output frequencies up to 175MHz,
the ICS86953I-147 is targeted for high performance clock ap-
plications. Along with a fully integrated PLL, the ICS86953I-147
contains frequency configurable outputs and an external feed-
back input for regenerating clocks with “zero delay”.
• Maximum output frequency: PLL Mode, 175MHz
• VCO range: 250MHz to 700MHz

single ended levels. The reference voltage V_REF = VDD/2 is the center of the input voltage swing. For example, if the input
generated by the bias resistors R1, R2 and C1.This bias circuit clock swing is only 2.5V andVDD = 3.3V, V_REF should be 1.25V

POWER SUPPLY FILTERING TECHNIQUES
As in any high speed analog circuitry, the power supply pins are
vulnerable to random noise.The ICS86953I-147 provides sepa-
rate power supplies to isolate any high switching noise from the
outputs to the internal PLL.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 2
illustrates how a 10Ω resistor along with a 10µF and a .01µF
bypass capacitor should be connected to each VDDA pin.

The following component footprints are used in this layout
example:
trace delay might be restricted by the available space on the board
and the component location.While routing the traces, the clock
signal traces should be routed first and should be locked prior to
routing other signal traces.
All the resistors and capacitors are size 0603.
P
OWER AND
G
ROUNDING
• The 50Ω output traces should have same length.
Place the decoupling capacitors as close as possible to the power
pins. If space allows, placement of the decoupling capacitor on
the component side is preferred.This can reduce unwanted in-
ductance between the decoupling capacitor and the power pin
caused by the via.
• Avoid sharp angles on the clock trace.Sharp angle turns
cause the characteristic impedance to change on
the transmission lines.
• Keep the clock traces on the same layer.Whenever pos-
sible, avoid placing vias on the clock traces. Placement
of vias on the traces can affect the trace characteristic
impedance and hence degrade signal integrity.
Maximize the power and ground pad sizes and number of vias
capacitors.This can reduce the inductance between the power
and ground planes and the component power and ground pins.
• To prevent cross talk, avoid routing other signal traces in
parallel with the clock traces. If running parallel traces is
unavoidable, allow a separation of at least three trace
widths between the differential clock trace and the other
signal trace.
The RC filter consisting of R7, C11, and C16 should be placed
as close to the VDDA pin as possible.

RACES AND
TERMINATION
Poor signal integrity can degrade the system performance or
cause system failure. In synchronous high-speed digital systems,
the clock signal is less tolerant to poor signal integrity than other
signals. Any ringing on the rising or falling edge or excessive ring
back can cause system failure. The shape of the trace and the
• Make sure no other signal traces are routed between the
clock trace pair.
• The series termination resistors should be located as
close to the driver pins as possible.
