APPLICATIONS INFORMATION
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS
Figure 2 shows how a differential input can be wired to accept
single ended levels.The reference voltageVREF =VDD/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 VDD = 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 VDD 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 50 applications, R3 and R4 can be 100Ω.
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 VDD + 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.

other differential signals. Both differential signals must meet component to confirm the driver termination requirements. For
the VPP and VCMR input requirements. Figures 3A to 3E show example in Figure 3A, the input termination applies for IDT
interface examples for the CLK/nCLK input driven by the most open emitter LVHSTL drivers. If you are using an LVHSTL

POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the ICS85214I.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS85214I 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 + 5ꢀ = 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 at the junction of the bond wire and bond pad 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 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 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,
