SNAS290D DECEMBER 2005REVISED APRIL 2013  
APPLICATION INFORMATION  
The LM98555 is a fully integrated clock driver/buffer for high speed CCD applications. It provides high  
performance low impedance drivers, with optimized low skew performance of the P1 and P2 outputs. Enable  
inputs allow use of two, four, six, or all eight P1 and P2 drivers to optimize the amount of drive for the application.  
The 64 pin thermally enhanced HTSSOP provides excellent power handling through the use of an exposed heat  
transfer pad on the underside of the package.  
THERMAL GUIDELINES  
The LM98555's maximum power dissipation limit, shown in Operating Conditions, must be strictly adhered to.  
The product's multiple high-strength drivers, with their ability to drive a wide-range of loads, make it possible to  
be within spec on each output and yet violate the aggregate maximum power dissipation limit for the total  
product. Special caution must be paid to this by limiting the chip's operating conditions (loads, power supply,  
number of parallel drivers enabled, frequency of operation) to make certain that the maximum power dissipation  
limit is never exceeded.  
Thermal characterization of the device has been done to provide reference points under specific conditions. θ  
junction to ambient was measured using a 5.5 inch by 3 inch, 4 layer PCB. The thermal contact pad on the board  
was connected using vias to a full ground plane on one of the internal layers. The recommended thermal pad is  
shown in Figure 4.  
Exposed thermal pad mounting area.  
3.81 mm  
5.81 mm  
Vias are 0.3 mm diameter at 1.2 mm pitch.  
Recommended via plating of 1 oz copper.  
Figure 4. Exposed Pad Land Pattern  
The vias shown provide a path for heat to flow from the pad to a heat sinking or dissipating area of the printed  
circuit board. The following figures show several typical examples of how this can be done, and illustrate how  
heat is conducted away from the IC to larger areas where it is dissipated.  
Vias couple thermal energy to internal ground plane to transfer heat away from package.

Vias couple thermal energy to copper plane on bottom layer to transfer heat away from package.  
Figure 7. 2 Layer PCB  
In multi-layer board applications, one or more internal planes are usually dedicated as a ground plane.  
Connecting the thermal pad to this ground plane with vias will usually provide adequate heat management. In 2  
layer boards, it is important to provide a large heat spreading pad on the opposite side of the board. The vias will  
provide a good thermal connection between the pad under the IC, and the heat spreading pad on the bottom of  
the board. Thermal modelling can be done using the θ junction to pad information provided, to calculate the  
required area of copper based on the ambient temperature of the system, and the calculated amount of thermal  
dissipation in the LM98555.  
POWER DISSIPATION  
The amount of power dissipated in the device can be determined by considering the following factors:  
Power dissipated delivering energy to the load capacitance  
Power dissipated delivering energy to parasitic capacitance  
Power dissipated due to leakage in the IC  
The amount of power dissipated due to leakage is very small in this CMOS device. Most of the power will be due  
to the load capacitance being switched, with a small additional amount caused by the parasitic capacitance of the  
output circuitry, output pins, and PCB traces. A typical parasitic capacitance would be on the order of 5 pF. Since  
the load capacitance will be on the order of 100 pF or more, this usually dominates the power dissipation  
calculation. The following equation can be used to calculate the power dissipation due to capacitive switching of  
the loads:  
P = Sum[Output Frequency x Load Capacitance x Output Voltage Squared] (summed for all outputs)  
INPUT SIGNALS  
Care should be taken to match the trace lengths between timing signals that require low skew. Usually, the P1A  
and P2A signals will be the most critical. In some applications, the timing of P2B with respect to P1A and P2A  
can also be important, and that input trace should also be carefully designed.  
Trace shape and width should also be carefully controlled. The trace geometry will determine the characteristic  
impedance of each trace. The impedance should be set to give reasonable immunity to noise coupling into the  
trace. With a known trace impedance, the signals can be terminated using a series resistor at the source that is  
equal to the characteristic impedance. This will provide a signal with minimum overshoot and ringing, and will  
contribute to better performance of the final signal reaching the CCD.  
OUTPUT CONNECTIONS AND LOADING EXAMPLES  
The LM98555 can be used with a wide variety of different CCD sensors. The P1Aoutx and P2Aoutx outputs can  
be selectively enabled to provide 2, 4, 6, or 8 drivers. This allows the available drive strength to be optimized for  
the sensor and application. Connecting multiple outputs together in parallel as shown in the typical application  
circuit provides lower drive impedance as needed to suit the load being driven. When driving smaller loads, lower  
switching noise will be generated if the minimum necessary outputs are enabled and used.  
The output signal traces should also be designed for a known impedance. Source terminating resistors should be  
used in series with each output to provide good matching to the trace characteristic impedance. The resistors  
should be located as close as possible to each output pin. If multiple outputs will be combined to drive a single  
load pin, the output signals should be combined after the termination resistors. This will provide the best  
summing of adjacent outputs. The combined signal should then pass through an EMI type ferrite bead. This  
component can be selected to change the bandwidth or shape of the clocking signal to achieve the best CCD  
transfer efficiency.

Several other techniques will also help maintain signal quality, and minimize timing differences between critical  
signals. Vias should not be used for critical timing signals. These can add impedance discontinuities that will  
affect the waveform quality. Traces should have gradual bends and avoid sharp changes in direction that can  
also introduce impedance discontinuities.  
SELECTIVE DRIVER ENABLING  
With the Enable pins, the user has the capability to enable only the drivers that are required for the application,  
thus eliminating unnecessary outputs switching. The following table shows the details.

P1Aout(1:0) and P2Aout(1:0) are enabled; all others disabled.

Note: The disabled drivers' outputs are in TRI-STATE.  
POWER SUPPLY SEQUENCING  
During device power-up and power-down, VDDI must be maintained less than (VDDO + 0.2V) to prevent excessive  
current flow through the internal ESD protection circuitry. Since most applications will involve 3V on VDDI and 5V  
on VDDO, this can be easily met. If this voltage relationship cannot be met, then the DC pin and package limits for  
input current must be maintained by controlling the source impedance of the VDDI supply.  
POWER AND GROUND - PLANES VERSUS BUSES  
The best performance will be achieved by using planes rather than traces for power and ground. Planes provide  
lower electrical and thermal impedance. Ground bounce and ringing are reduced, electromagnetic emissions are  
minimized and the best thermal performance will be realized.  
A single common ground plane should be used for all power and signal domains.  
Another circuit board layer can be used to provide power to the various circuitry. Different power buses can be  
provided by isolated planes within this layer of the circuit board.  
EMI MANAGEMENT  
Good EMI control will be achieved by addressing the following items:  
Provide proper source termination of output signals  
Limit length of output traces  
Ensure adequate power supply decoupling  
Provide power and ground planes as much as possible  
Provide common ground plane for all signals, especially between LM98555 outputs and load CCD  
Enable and use the minimum number of outputs needed

(1) 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.  
(2) 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)  
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4)  
Multiple Top-Side Markings will be inside parentheses. Only one Top-Side Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a  
continuation of the previous line and the two combined represent the entire Top-Side Marking for that device.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of  
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
