Fanout Buffer and a member of the
HiPerClockS™ family of High Performance
Clock Solutions from IDT. The PCLK, nPCLK
• PLCK, nPLCK pair can accept the following
differential input levels: LVPECL, LVDS, CML, SSTL
pair can accept LVPECL, CML and SSTL differential input
levels.The ICS853111-01 is characterized to operate from
a 3.3V power supply. Guaranteed output and part-to-part
skew characteristics make the ICS853111-01 ideal for
those clock distribution applications demanding well
defined performance and repeatability.

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

POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the ICS853111-01.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS853111-01 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 * 75mA = 285mW
Power (outputs)MAX = 30.94mW/Loaded Output pair
If all outputs are loaded, the total power is 9 * 30.94mW = 278.5mW
Total Power_MAX (3.8V, with all outputs switching) = 285mW + 278.5mW = 563.5mW
2. JunctionTemperature.
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 31.1°C/W perTable 5 below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.564W * 31.1°C/W = 102°C. This is well 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).

To calculate worst case power dissipation into the load, use the following equations which assume a 50Ω load, and a termination
voltage of V - 2V.
