ICS
HiPerClockS™
mance Differential-to-3.3V LVPECL / ECL Clock
Generator/Divider and a member of the
HiPerClockS™ family of High Performance Clock
Solutions from ICS. The ICS87339-01 has one
two divide by 4/6 differential 3.3V LVPECL outputs
• One differential CLK, nCLK input pair
• CLK, nCLK pair can accept the following differential
input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
differential clock input pair. The CLK, nCLK pair can accept
most standard differential input levels. The clock enable is
internally synchronized to eliminate runt pulses on the
outputs during asynchronous assertion/deassertion of the
clock enable pin.
• Maximum input frequency: 1GHz
• Translates any single ended input signal (LVCMOS, LVTTL,
GTL) to LVPECL levels with resistor bias on nCLK input
Guaranteed output and part-to-part skew characteristics
make the ICS87339-01 ideal for clock distribution applications
demanding well defined performance and repeatability.
• Output skew: 35ps (maximum)
• Part-to-part skew: 385ps (maximum)
• Bank skew: Bank A - 30ps (maximum)
Bank B - 25ps (maximum)

APPLICATION INFORMATION
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS
Figure 2 shows how the differential input can be wired to accept
single ended levels. The reference voltage V_REF = VCC/2 is
generated by the bias resistors R1, R2 and C1.This bias circuit
should be located as close as possible to the input pin.The ratio
of R1 and R2 might need to be adjusted to position the V_REF
in the center of the input voltage swing. For example, if the
input clock swing is only 2.5V and VCC = 3.3V, V_REF should be
1.25V and R2/R1 = 0.609.

TERMINATION FOR LVPECL OUTPUTS
The clock layout topology shown below is a typical termi-
nation for LVPECL outputs. The two different layouts men-
tioned are recommended only as guidelines.
ance techniques should be used to maximize operating
frequency and minimize signal distortion. Figures 4A and
4B 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 ICS87339-01.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS87339-01 is the sum of the core power plus the power dissipated in the load(s).
The following is the power dissipation for VCC = 3.3V + 0.3V = 3.6V, 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 * ICC_MAX = 3.6V * 105mA = 378
Power (outputs)MAX = 30mW/Loaded Output pair
If all outputs are loaded, the total power is 4 * 30mW = 120mW
Total Power_MAX (3.6V, with all outputs switching) = 378mW + 120mW = 498mW
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 = Junction Temperature
θJA =Junction-to-AmbientThermal Resistance
Pd_total = Total Device Power Dissipation (example calculation is in section 1 above)
TA = Ambient Temperature
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 39.7°C/W perTable 6 below.
Therefore, Tj for an ambient temperature of 70°C with all outputs switching is:
70°C + 0.498W * 39.7°C/W = 89.8°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).
