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

DIFFERENTIAL CLOCK INPUT INTERFACE
The CLK /nCLK accepts LVDS, LVPECL, HSTL, SSTL, HCSL
and other differential signals. Both VSWING and VOH must meet the
VPP and VCMR input requirements. Figures 3A to 3D show inter-
face examples for the ICS85214 clock input driven by the most
common driver types. The input interfaces suggested here are
examples only. Please consult with the vendor of the driver com-
ponent to confirm the driver termination requirements. For ex-
ample in Figure 3A, the input termination applies for ICS
HiPerClockS HSTLdrivers. If you are using an HSTL driver from
another vendor, use their termination recommendations.

POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the ICS85214.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS85214 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 * 80mA = 227.2mW
Power (outputs)MAX = 32.8mW/Loaded Output pair
If all outputs are loaded, the total power is 5 * 32.8mW = 164mW
Total Power_MAX (3.465V, with all outputs switching) = 227.2mW + 164mW = 391.2mW
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 = 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 + 0.391W * 66.6°C/W = 111°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).
