Recommendations for Unused Output Pins  
Outputs:  
LVHSTL Outputs  
All unused LVHSTL outputs can be left floating. We recommend that  
there is no trace attached. Both sides of the differential output pair  
should either be left floating or terminated.  
Wiring the Differential Input to Accept Single-Ended Levels  
Figure 1 shows how a differential input can be wired to accept single  
ended levels. The reference voltage VREF = VCC/2 is generated by the  
bias resistors R1 and R2. The bypass capacitor (C1) is used to help  
filter noise on the DC bias. This bias circuit should be located as close  
to the input pin as possible. The ratio of R1 and R2 might need to be  
adjusted to position the VREF in the center of the input voltage swing.  
For example, if the input clock swing is 2.5V and VCC = 3.3V, R1 and  
R2 value should be adjusted to set VREF at 1.25V. The values below  
are for when both the single ended swing and VCC are at the same  
voltage. This configuration requires that the sum of the output  
impedance of the driver (Ro) and the series resistance (Rs) equals  
the transmission line impedance. In addition, matched termination at  
the input will attenuate the signal in half. This can be done in one of  
two ways. First, R3 and R4 in parallel should equal the transmission  
line impedance. For most 50applications, R3 and R4 can be 100.  
The values of the resistors can be increased to reduce the loading for  
slower and weaker LVCMOS driver. When using single-ended  
signaling, the noise rejection benefits of differential signaling are  
reduced. Even though the differential input can handle full rail  
LVCMOS signaling, it is recommended that the amplitude be  
reduced. The datasheet specifies a lower differential amplitude,  
however this only applies to differential signals. For single-ended  
applications, the swing can be larger, however VIL cannot be less  
than -0.3V and VIH cannot be more than VCC + 0.3V. Though some  
of the recommended components might not be used, the pads should  
be placed in the layout. They can be utilized for debugging purposes.  
The datasheet specifications are characterized and guaranteed by  
using a differential signal.

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 2A to 2F show interface  
examples for the 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 2A, the input  
termination applies for IDT open emitter LVHSTL drivers. If you are  
using an LVHSTL driver from another vendor, use their termination  
recommendation.

Power Considerations  
This section provides information on power dissipation and junction temperature for the ICS85211BI-03.  
Equations and example calculations are also provided.  
1. Power Dissipation.  
The total power dissipation for the ICS85211BI-03 is the sum of the core power plus the power dissipated in the load(s).  
The following is the power dissipation for VDD= 3.3V + 5% = 3.465V, which gives worst case results.  
NOTE: Please refer to Section 3 for details on calculating power dissipated in the load.  
Power (core)MAX = VDD_MAX * IDD_MAX = 3.465V * 55mA = 190.6mW  
Power (outputs)MAX = 77.76mW/Loaded Output pair  
If all outputs are loaded, the total power is 2 * 77.76mW = 155.52mW  
Total Power_MAX (3.3V, with all outputs switching) =190.6mW + 155.52mW = 346.12mW  
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 is 125°C. Limiting the internal transistor junction temperature, Tj, to 125°C ensures that the bond  
wire and bond pad temperature remains below 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 103.3°C/W per Table 6 below.  
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:  
85°C + 0.346W * 103.3°C/W = 120.7°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 (multi-layer).

Figure 4. LVHSTL Driver Circuit and Termination  
To calculate worst case power dissipation into the load, use the following equations which assume a 50load.  
Pd_H is power dissipation when the output drives high.  
Pd_L is the power dissipation when the output drives low.  
Pd_H = (VOH_MAX/ RL) * (VDD_MAX – (VOH_MAX  
)
Pd_L = (VOL_MAX/ RL) * (VDD_MAX – (VOL_MAX  
)
Pd_H = (1.15V/50) * (3.465V – 1.15V) = 53.24mW  
Pd_L = (0.4V/50) * (3.465V – 0.4V) = 24.52mW  
Total Power Dissipation per output pair = Pd_H + Pd_L = 77.76mW
