12:2, DIFFERENTIAL-TO-LVDS MULTIPLEXER
ICS854S202I
GENERAL DESCRIPTION
FEATURES
The ICS854S202I is a 12:2 Differential-to-LVDS
• Two differential 3.3V LVDS clock outputs
ICS
Clock Multiplexer which can operate >3GHz and
is a member of the HiPerClockS™ family of High
Performance Clock Solutions from IDT. The
ICS854S202I has 12 selectable differential clock
• Twelve selectable differential clock inputs
HiPerClockS™
• CLKx, nCLKx pairs can accept the following differential input
levels: LVPECL, LVDS, HSTL, SSTL, HCSL
inputs, any of which can be independently routed to either of
the two LVDS outputs. The CLKx, nCLKx input pairs can
accept LVPECL, LVDS, CML or SSTL levels. The fully differen-
tial architecture and low propagation delay make it ideal for
use in clock distribution circuits.

ADDITIVE PHASE JITTER
band to the power in the fundamental. When the required offset
is specified, the phase noise is called a dBc value, which simply
means dBm at a specified offset from the fundamental. By
investigating jitter in the frequency domain, we get a better
understanding of its effects on the desired application over the
entire time record of the signal. It is mathematically possible to
calculate an expected bit error rate given a phase noise plot.
The spectral purity in a band at a specific offset from the
fundamental compared to the power of the fundamental is called
the dBc Phase Noise. This value is normally expressed using a
Phase noise plot and is most often the specified plot in many
applications.Phase noise is defined as the ratio of the noise power
present in a 1Hz band at a specified offset from the fundamental
frequency to the power value of the fundamental. This ratio is
expressed in decibels (dBm) or a ratio of the power in the 1Hz
Additive Phase Jitter @ 155.5MHz
(12kHz to 20MHz) = 0.16ps (typical)
OFFSET FROM CARRIER FREQUENCY (HZ)
As with most timing specifications, phase noise measurements
have issues. The primary issue relates to the limitations of the
equipment. Often the noise floor of the equipment is higher than
the noise floor of the device. This is illustrated above. The device
meets the noise floor of what is shown, but can actually be lower.
The phase noise is dependant on the input source and
measurement equipment.

APPLICATION INFORMATION
RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
INPUTS:
OUTPUTS:
CLK/nCLK INPUT:
LVDS OUTPUT
For applications not requiring the use of the differential input,
both CLK and nCLK can be left floating. Though not required, but
for additional protection, a 1kΩ resistor can be tied from CLK to
ground.
All unused LVDS output pairs can be either left floating or
terminated with 100Ω across. If they are left floating, we
recommend that there is no trace attached.
LVCMOS CONTROL PINS:
All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1kΩ resistor can be used.
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS
Figure 1 shows how the differential input can be wired to accept
single ended levels. The reference voltage V_REF = V /2 is
generated by the bias resistors R1, R2 and C1. This bias DcDircuit
should be located as close as possible to the input pin. The ratio
of R1 and R2 might need to be adjusted to position the V_REF in
the center of the input voltage swing. For example, if the input
clock swing is only 2.5V and V = 3.3V, V_REF should be 1.25V

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 2E 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 2A, the input termination applies for IDT
HiPerClockS 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 ICS854S202I-01.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS854S202I-01 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.

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 60.4°C/W per Table 6 below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.399W * 60.4°C/W = 109.1°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).
