DESCRIPTION
The CDCLVD2108 clock buffer distributes two clock
inputs (IN0, IN1) to a total of 16 pairs of differential
LVDS clock outputs (OUT0, OUT15). Each buffer
block consists of one input and 8 LVDS outputs. The
inputs can either be LVDS, LVPECL, or LVCMOS.
The CDCLVD2108 is specifically designed for driving
50-Ω transmission lines. In case of driving the inputs
in single ended mode, the appropriate bias voltage
(VAC_REF) should be applied to the unused negative
input pin.
Using the control pin (EN) outputs can be either
disabled or enabled. If the EN pin is left open all
outputs are active, if switched to a logical '0' all
outputs are disabled (static logical 0), if switched to a
logical '1', OUT (8..15) are switched off and OUT
(0..7) are active. The part supports a fail safe
function. It incorporates an input hysteresis, which
prevents random oscillation of the outputs in absence
of an input signal.
The device operates in 2.5V supply environment and
is characterized from –40°C to 85°C (ambient
temperature). The CDCLVD2108 is packaged in
small 48-pin, 7-mm x 7-mm QFN package.

APPLICATION INFORMATION
THERMAL MANAGEMENT
For reliability and performance reasons, the die temperature should be limited to a maximum of 125°C.
The device package has an exposed pad that provides the primary heat removal path to the printed circuit board
(PCB). To maximize the heat dissipation from the package, a thermal landing pattern including multiple vias to a
ground plane must be incorporated into the PCB within the footprint of the package. The thermal pad must be
soldered down to ensure adequate heat conduction to of the package. Check the mechanical data at the end of
the data sheet for land and via pattern examples.
POWER-SUPPLY FILTERING
High-performance clock buffers are sensitive to noises on the power supply, which can dramatically increase the
additive jitter of the buffer. Thus, it is essential to reduce noise from the system power supply, especially when
jitter/phase noise is very critical to the application.
Filter capacitors are used to eliminate the low-frequency noise from the power supply, where the bypass
capacitors provide the very low impedance path for high-frequency noise and guard the power-supply system
against the induced fluctuations. These bypass capacitors also provide instantaneous current surges as required
by the device and should have low equivalent series resistance (ESR). To properly use the bypass capacitors,
they must be placed very close to the power-supply pins and laid out with short loops to minimize inductance. It
is recommended to add as many high-frequency (for example, 0.1 mF) bypass capacitors as there are supply
pins in the package. It is recommended, but not required, to insert a ferrite bead between the board power supply
and the chip power supply that isolates the high-frequency switching noises generated by the clock driver; these
beads prevent the switching noise from leaking into the board supply. Choose an appropriate ferrite bead with
very low dc resistance because it is imperative to provide adequate isolation between the board supply and the
chip supply, as well as to maintain a voltage at the supply pins that is greater than the minimum voltage required
for proper operation.

LVDS OUTPUT TERMINATION
The proper LVDS termination for signal integrity over two 50 Ω lines is 100 Ω between the outputs on the
receiver end. Either dc-coupled termination or ac-coupled termination can be used for LVDS outputs. It is
recommended to place termination resister close to the receiver. If the receiver is internally biased to a voltage
different than the output common mode voltage of the CDCLVD2108, ac-coupling should be used. If the LVDS
receiver has internal 100 Ω termination, external termination must be omitted.
Unused outputs can be left open without connecting any trace to the output pins.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
