DIFFERENTIAL-TO-3.3V LVPECL CLOCK GENERATOR
GENERAL DESCRIPTION
FEATURES
The ICS87339I-11 is a low skew, high perfor- • Dual ÷2, ÷4 differential 3.3V LVPECL outputs;
ICS
mance Differential-to-3.3V LVPECL Clock Gen-
erator/Divider and a member of the HiPerClockS™
family of High Performance Clock Solutions
from IDT. The ICS87339I-11 has one differen-
Dual ÷4, ÷5, ÷6 differential 3.3V LVPECL outputs
HiPerClockS™
• One differential CLK, nCLK input pair
• CLK, nCLK pair can accept the following differential
input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
tial 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 clock 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 ICS87339I-11 ideal for clock distribution applica-
tions demanding well defined performance and repeatability.
• Output skew: 35ps (maximum)
• Part-to-part skew: 385ps (maximum)
• Bank skew: Bank A - 20ps (maximum)
Bank B - 20ps (maximum)
• Propagation delay: 2.1ns (maximum)
• LVPECL mode operating voltage supply range:
VCC = 3V to 3.6V, VEE = 0V
• Available in both standard (RoHS5) and lead-free (RoHS 6)

POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the ICS87339I-11.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS87339I-11 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 = 378mW
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 = 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 66.6°C/W perTable 6A below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.498W * 66.6°C/W = 118.1°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).
