Data Sheet
to-LVCMOS/ LVTTL Fanout Buffer
General Description
Features
The 83948I-147 is a low skew, 1-to-12 Differential-to-LVCMOS/LVT-
TL Fanout Buffer. The 83948I-147 has two selectable clock inputs.
The CLK, nCLK pair can accept most standard differential input lev-
els. The LVCMOS_CLK can accept LVCMOS or LVTTL input levels.
The low impedance LVCMOS/LVTTL outputs are designed to drive
50 series or parallel terminated transmission lines. The effective fa-
nout can be increased from 12 to 24 by utilizing the ability of the out-
puts to drive two series terminated lines.
• Twelve LVCMOS/LVTTL outputs
• Selectable differential CLK/nCLK or LVCMOS/LVTTL clock input
• CLK/nCLK pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
• LVCMOS_CLK supports the following input types:
LVCMOS, LVTTL
• Output frequency: 350MHz
The 83948I-147 is characterized at full 3.3V, full 2.5V or mixed 3.3V
core/2.5V output operating supply modes. Guaranteed output and
part-to-part skew characteristics make the 83948I-147 ideal for those
clock distribution applications demanding well defined performance
and repeatability.
• Additive phase jitter, RMS: 0.14ps (typical)
• Output skew: 100ps (maximum), 3.3V 5%
• Part-to-part skew: 1ns (maximum), 3.3V 5%
• Operating supply modes:
• Core/Output
3.3V/3.3V
3.3V/2.5V
2.5V/2.5V
• -40°C to 85°C ambient operating temperature
• Lead-free (RoHS 6) packaging

Additive Phase Jitter
The spectral purity in a band at a specific offset from 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.
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 band to the power in the
Additive Phase Jitter, RMS
@ 155.52MHz (12kHz to 20MHz) =
0.14ps (typical)
Offset From Carrier Frequency (Hz)
As with most timing specifications, phase noise measurements has
issues relating 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 dependent on
the input source and measurement equipment.

Application Information
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 = VDD/2 is
generated by the bias resistors R1, R2 and C1. This bias circuit
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 VDD = 3.3V, V_REF should be 1.25V and R2/R1 =

Outputs:
CLK/nCLK Inputs
LVCMOS Outputs
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 1k resistor can be tied from CLK to ground.
All unused LVCMOS output can be left floating. There should be no
trace attached.
CLK Input
For applications not requiring the use of a clock input, it can be left
floating. Though not required, but for additional protection, a 1k
resistor can be tied from the CLK input to ground.
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 1k resistor can be used.

Differential Clock Input Interface
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL and
other differential signals. Both signals 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.
