PCI EXPRESS/JITTER ATTENUATOR  
ICS874001I-02  
GENERAL DESCRIPTION  
FEATURES  
The ICS874001I-02 is a high performance Jitter  
One differential LVDS output pair  
ICS  
HiPerClockS™  
Attenuator designed for use in PCI Express™ sys-  
tems. In some PCI Express systems, such as those  
found in desktop PCs, the PCI Express clocks are  
generated from a low bandwidth, high phase noise  
PLL frequency synthesizer. In these systems, a jitter  
One differential clock input  
CLK and nCLK supports the following input types:  
LVPECL, LVDS, LVHSTL, SSTL, HCSL  
Output frequency range: 98MHz - 640MHz  
Input frequency range: 98MHz - 128MHz  
VCO range: 490MHz - 640MHz  
attenuator may be required to attenuate high frequency random  
and deterministic jitter components from the PLL synthesizer  
and from the system board. The ICS874001I-02 has 2 PLL  
bandwidth modes: 2.2MHz and 3MHz. The 2.2MHz mode will  
provide maximum jitter attenuation, but with higher PLL tracking  
skew and spread spectrum modulation from the motherboard  
synthesizer may be attenuated. The 3MHz bandwidth provides  
the best track-ing skew and will pass most spread profiles, but  
the jitter attenuation will not be as good as the lower bandwidth  
modes. The 874001I-02 can be set for different modes using the  
F_SELx pins, as shown in Table 3C.  
Cycle-to-cycle jitter: 50ps (maximum) design target  
3.3V or 2.5V operating supply  
Two bandwidth modes allow the system designer to make  
jitter attenuation/tracking skew design trade-offs  
-40°C to 85°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)  
The ICS874001I-02 uses IDT’s 3rd Generation FemtoClockTM  
PLL technology to achive the lowest possible phase noise.  
The device is packaged in a small 20-pin TSSOP package,  
making it ideal for use in space constrained applications such as  
PCI Express add-in cards.

APPLICATION INFORMATION  
POWER SUPPLY FILTERING TECHNIQUES  
As in any high speed analog circuitry, the power supply pins  
are vulnerable to random noise. The ICS874001I-02  
provides separate power supplies to isolate any high switching  
noise from the outputs to the internal PLL. VDD, VDDA, and VDDO  
should be individually connected to the power supply plane  
through vias, and bypass capacitors should be used for each  
pin. To achieve optimum jitter performance, power supply iso-  
lation is required. Figure 1 illustrates how a 10resistor along  
with a 10µF and a .01µF bypass capacitor should be con-  
nected to each VCCA pin.

to position the V_REF in the center of the input voltage swing.  
V_REF = V /2 is generated by the bias resistors R1, R2 and  
C1. This bias circuit should be located as close as possible to  
For example, if the input clock swing is only 2.5V and V  
3.3V, V_REF should be 1.25V and R2/R1 = 0.609.

DIFFERENTIAL CLOCK INPUT INTERFACE  
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL  
and other differential signals. Both VSWING and VOH must meet the  
VPP and VCMR input requirements. Figures 3A to 3D show interface  
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 3A, the input termination applies for IDT  
HiPerClockS LVHSTL drivers. If you are using an LVHSTL driver  
from another vendor, use their termination recommendation.

A general LVDS interface is shown in Figure 4. In a 100Ω  
differential transmission line environment, LVDS drivers  
require a matched load termination of 100across near  
the receiver input. For a multiple LVDS outputs buffer, if only  
partial outputs are used, it is recommended to terminate the  
unused outputs.

POWER CONSIDERATIONS  
This section provides information on power dissipation and junction temperature for the ICS874001I-02.  
Equations and example calculations are also provided.  
1. Power Dissipation.  
The total power dissipation for the ICS874001I-02 is the sum of the core power plus the power dissipated in the load(s).  
The following is the power dissipation for V = 3.3V + 5ꢀ = 3.465V, which gives worst case results.  
DD  
Power (core) = V  
* (I  
+ I  
) = 3.465V * (60mA + 10mA) = 242.55mW

DDO_MAX  
Total Power  
= 242.55mW + 69.3mW = 311.85mW  
_MAX  
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  
TM  
device. The maximum recommended junction temperature for HiPerClockS devices is 125°C.  
The equation for Tj is as follows: Tj = θJA * Pd_total + TA  
Tj = Junction Temperature  
θJA = Junction-to-Ambient Thermal 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 66.6°C/W per Table 6 below.  
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:  
85°C + 0.312W * 66.6°C/W = 105.8°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).
