GENERAL DESCRIPTION
FEATURES
The ICS85356I is a dual 2:1 Differential-to-LVPECL • High speed differential multiplexer.
ICS
Multiplexer and is a member of the HiPerClockSTM
family of High Performance Clock Solutions from
ICS.The device has both common select and indi-
vidual select inputs.When COM_SEL is logic High,
The device can be configured as a 2:1 multiplexer
HiPerClockS™
• Dual 3.3V LVPECL outputs
• Selectable differential CLKxx, nCLKxx inputs
the CLKxx input pairs will be passed to the output. When
COM_SEL is logic Low, the output is determined by the setting
of the SEL0 pin for channel 0 and the SEL1 pin for Channel 1.
• CLKxx, nCLKxx pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
• Output frequency: 900MHz (typical)
The differential input has a common mode range that can accept
most differential input types such as LVPECL, LVDS, LVHSTL,
SSTL, and HCSL. The ICS85356I can therefore be used as a
differential translator to translate almost any differential input type
• Translates any single ended input signal to 3.3V
LVPECL levels with resistor bias on nCLKxx input
• Output skew: 75ps (typical)
to LVPECL. It can also be used in ECL mode by setting V =0V
CC
• Propagation delay: 1.15ns (typical)
and VEE to -3.0V to - 3.8V.
• LVPECL mode operating voltage supply range:
The ICS85356I adds negligible jitter to the input clock and can
operate at high frequencies in excess of 900MHz thus making
it ideal for use in demanding applications such as SONET,
Fibre Channel, 1 Gigabit/10 Gigabit Ethernet.
VCC = 3V to 3.8V, VEE = 0V
• ECL mode operating voltage supply range:
VCC = 0V, VEE = -3V to -3.8V
• -40°C to 85°C ambient operating temperature
• Lead-Free package available
• Compatible with MC100LVEL56

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 theV_REF in
the center of the input voltage swing. For example, if the input
clock swing is only 2.5V andVCC = 3.3V, V_REF should be 1.25V
and R2/R1 = 0.609.

50Ω transmission lines. Matched impedance techniques should
be used to maximize operating frequency and minimize signal
distortion. Figures 2A and 2B show two different layouts which
are recommended only as guidelines. Other suitable clock lay-
outs 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 gen-
erate ECL/LVPECL compatible outputs.Therefore, terminating
resistors (DC current path to ground) or current sources must
be used for functionality. These outputs are designed to drive

POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the ICS85356I.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS85356I 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 * IEE_MAX = 3.6V * 40mA = 144mW
Power (outputs)MAX = 30.2mW/Loaded Output pair
If all outputs are loaded, the total power is 2 * 30.2mW = 60.4mW
Total Power_MAX (3.6V, with all outputs switching) = 144mW + 60.4mW = 204.4mW
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 39.7°C/W perTable 6A below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.204W * 39.7°C/W = 93.1°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).
