ADDITIVE PHASE JITTER
the 1Hz band to the power in the fundamental. When the re-
quired offset is specified, the phase noise is called a dBc value,
which simply means dBm at a specified offset from the funda-
mental. By investigating jitter in the frequency domain, we get a
better understanding of its effects on the desired application over
the entire time record of the signal. It is mathematically possible
to calculate an expected bit error rate given a phase noise plot.
The spectral purity in a band at a specific offset from the funda-
mental compared to the power of the fundamental is called the
dBc Phase Noise. This value is normally expressed using a
Phase noise plot and is most often the specified plot in many
applications. Phase noise is defined as the ratio of the noise
power present in a 1Hz band at a specified offset from the fun-
damental frequency to the power value of the fundamental.This
ratio is expressed in decibels (dBm) or a ratio of the power in

APPLICATION INFORMATION
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS
Figure 1 shows how the differential input can be wired to accept of R1 and R2 might need to be adjusted to position theV_REF in
single ended levels. The reference voltage V_REF ~ VCC/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 andVCC = 3.3V, V_REF should be 1.25V
should be located as close as possible to the input pin.The ratio and R2/R1 = 0.609.

RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
OUTPUTS:
INPUTS:
LVPECL OUTPUT
CLK/nCLK INPUT:
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.
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 1kΩ resistor can be tied from
CLK to ground.

DIFFERENTIAL CLOCK INPUT INTERFACE
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL
and other differential signals.BothVSWING andVOH must meet the
VPP and VCMR input requirements. Figures 2A to 2E show inter-
face examples for the HiPerClockS CLK/nCLK input driven by
the most common driver types.The input interfaces suggested
here are examples only. Please consult with the vendor of the
driver component to confirm the driver termination requirements.
For example in Figure 2A, the input termination applies for ICS
HiPerClockS LVHSTL drivers. If you are using an LVHSTL driver
from another vendor, use their termination recommendation.

TERMINATION FOR LVPECL OUTPUTS
The clock layout topology shown below is a typical termina-
tion for LVPECL outputs.The two different layouts mentioned
are recommended only as guidelines.
ance techniques should be used to maximize operating
frequency and minimize signal distortion. Figures 3A and
3B show two different layouts which are recommended only
as guidelines. Other suitable clock layouts may exist and it
would be recommended that the board designers simulate
to guarantee compatibility across all printed circuit and clock
component process variations.
FOUT and nFOUT are low impedance follower outputs that
generate ECL/LVPECL compatible outputs. Therefore, ter-
minating resistors (DC current path to ground) or current
sources must be used for functionality. These outputs are
designed to drive 50Ω transmission lines. Matched imped-

POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the ICS85310I-01.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS85310I-01 is the sum of the core power plus the power dissipated in the load(s).
The following is the power dissipation for VCC = 3.8V, which gives worst case results.
NOTE: Please refer to Section 3 for details on calculating power dissipated in the load.
•
•
Power (core)MAX = VCC_MAX * IEE_MAX = 3.8V * 120mA = 456mW
Power (outputs)MAX = 30.2mW/Loaded Output pair
If all outputs are loaded, the total power is 10 * 30.2mW = 302mW
Total Power_MAX (3.8V, with all outputs switching) = 456mW + 302mW = 758mW
2. Junction Temperature.
Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad and directly affects the reliability of the
device.The maximum recommended junction temperature for HiPerClockSTM devices is 125°C.
The equation for Tj is as follows: Tj = θJA * Pd_total + TA
Tj = JunctionTemperature
θJA = Junction-to-AmbientThermal Resistance
Pd_total = Total Device Power Dissipation (example calculation is in section 1 above)
TA = AmbientTemperature
In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance θJA must be used. Assuming a
moderate air flow of 200 linear feet per minute and a multi-layer board, the appropriate value is 42.1°C/W perTable 5 below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.758W * 42.1°C/W = 117°C. This is below the limit of 125°C.
This calculation is only an example.Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow,
and the type of board (single layer or multi-layer).
