General Description
The LMK03002C Evaluation Board simplifies evaluation of the LMK03002C Precision Clock
Conditioner with Integrated VCO. The package consists of an evaluation board and CodeLoader
software. The CodeLoader software will run on a Windows 2000 or Windows XP PC. The purpose of
the CodeLoader software is to program the internal registers of the LMK03002C device through a
MICROWIRE
TM
interface.
The LMK0300xC PCB works for many LMK0300xC devices. Because of this the silkscreen on
the board is different from actual clock outputs in the datasheet and in CodeLoader. Refer to the
table below for the correct mapping.

Board Information
OSCin
By default the board is configured to use the on-board crystal oscillator. It is also possible to use the
board with a single ended or differential reference source at the OSCin port. Below are several
possible configurations for driving OSCin.
OSCin using on board crystal oscillator [default]
0 ohm R8, R11, R20 [power to crystal oscillator], R109
39 ohm R9 [can also be 0 ohm – depends on oscillator output power, 39 ohms
to be a voltage divider]

Features of the board
• Either one of two loop filters can be selected by shorting either R22 or R5. More info
about each loop filter can be found in the General Description and Appendix A.
• Test points for each of the uWire lines are scattered in the lower left corner of the board
and include: GOE_TP, DATAuWire, CLKuWire, LEuWire, SYNC_TP, and LD_TP.
• Ground is located on the unstuffed 10 pin header on the left side of the board.
• Ground is located on the GND_tp2 in the upper left corner of the board and GND_tp1
located to the right of the Vcc SMA connector.
• Ground is located on the bottom side of the board on each pad of the unstuffed 10 pin
header GND_J2.
• Vcc is located on the unstuffed 10 pin header on the upper left side of the board.
• Vcc is located on VccPlane test point located to the right of the Vcc SMA.
• Vcc is located on the bottom side of the board on each pad of the unstuffed 10 pin
header VCC_J2
Other Important Notes
• When changing the OSCin frequency, the OSCin frequency register needs to be changed
to match.
• Toggle the SYNC* pin to synchronize the clock outputs when in divided mode.
• For both loop filters, a helper silkscreen is offset from the loop filters to help identify the
components according to National Semiconductor’s traditional reference designators
associated with loop filters.
• The LMK0300xC PCB works for many LMK0300xC devices. Because of this the
silkscreen on the board is different from actual clock outputs in the datasheet and in
CodeLoader. Refer to the table below for the correct mapping.

Recommended Equipment
Power Supply
The Power Supply should be a low noise power supply. An Agilent 6623A Triple power supply with LC
filters on the output to reduce noise was used in creating these evaluation board instructions.
Phase Noise / Spectrum Analyzer
For measuring phase noise an Agilent E5052A is recommended. An Agilent E4445A PSA Spectrum
Analyzer with the Phase Noise option is also usable although the architecture of the E5052A is superior
for phase noise measurements. At frequencies less than 100 MHz the local oscillator noise of the PSA
is too high and measurements will be of the local oscillator, not the device under test.
Oscilloscope
For measuring delay an Agilent Infiniium DSO81204A was used.
Reference Oscillator
The on board crystal oscillator will provide a low noise reference signal to the device at offsets greater
than 1 kHz.
Note: The default loop filter has a loop bandwidth of ~105 kHz. Inside the loop bandwidth of a PLL the
noise is greatly affected by any noise on the reference oscillator (OSCin). Therefore any noise on the
oscillator less than ~105 kHz will be passed through and seen on the outputs. For this reason the main
output of a Signal Generator is not recommended for driving OSCin in this setup.

CodeLoader Settings
The Port Setup tab tells CodeLoader what signals are assigned to which pins. If this is wrong,
the part will not program.
Part setup can be restored to the default state by clicking Mode “16 MHz OSCin” The default
reference oscillator used for these instructions is 16 MHz and the restored mode expects a 16
MHz OSCin signal. For the loaded mode to take affect the device must be loaded by
pressing Ctrl+L.

The Registers tab shows the raw bits which will be programmed when device is loaded by
clicking Keyboard Controls Load Device or Ctrl+L.
The Clock Outputs tab allows the user to visualize the clock distribution portions of the device.
From this tab the device’s dividers, delays, clock output muxes, and output drivers can be
programmed along with internal loop filter values. The PLL block shows the R and N divider
values however to change these values either click on the PLL tab or the blue PLL box to access
the PLL tab to make changes to the PLL.

The PLL tab shows a conventional PLL diagram along with the VCO Divider. It is important to
realize that the total effective N value is PLL N Counter * VCO Divider. This means that the
“channel spacing” is the Phase Detector Frequency * VCO Divider. Depending on the
situation, this may require the R Counter multiplied up by the value of the VCO Divider to achieve
desired VCO output frequencies.
Example: If the desired VCO output frequency was 1648 MHz, R would need to be increased to
2 before 1648 MHz could be programmed because of the VCO Divider of 2 would only allow
programming of 1600, 1632, 1664, etc. with a 16 MHz phase detector frequency – because
changing the N counter from 51 to 52 changes to total N by two, 102 to 104!

Appendix A: VCO Performance
The internal VCO performance is measured by using a narrow bandwidth loop filter. By default
the narrow loop bandwidth filter is stuffed as Loop Filter #2 in positions C1_AUX, C2_AUX,
C2p_AUX, and R2_AUX and has a loop bandwidth of 55 Hz.
See the Loop Filter section in Board Options for more detail about switching between the two
different loop filters.

This loop filter is located on the top side of the PCB and is selected by placing a
0 ohm resistor on pad R5.
This loop filter has been designed with a very small loop bandwidth to minimize
the PLL from interacting with the noise of the VCO to permit a VCO phase noise
measurement.

VCO Phase Noise – Narrow Loop Bandwidth
This plot shows the noise of the VCO at 1632 MHz using a 500 kHz Phase
Detector Frequency. An external oscillator was used for this plot, since the VCO
noise dominates, reference oscillator noise is not critical.
The loop bandwidth has been minimized so that the VCO is the dominant noise
contributor.
10 Hz – 20 MHz integrated RMS jitter = 107.6 ps
100 Hz – 20 MHz integrated RMS jitter = 28.1 ps (shown)
1 kHz – 20 MHz integrated RMS jitter = 2.7 ps
12 kHz – 20 MHz integrated RMS jitter = 0.303 ps

Appendix B: Impact of Reference on Phase Noise
Inside the loop bandwidth of a PLL the phase noise is set by the quality of the
reference oscillator used. For this reason it is important to select a reference
oscillator suitable for the application.
Test Setup
Using the same loop filter as described in the General Description and by driving
the OSCin frequency with an ultra low jitter 100 MHz Wetzel Crystal (501-
04517D) and setting R = 5 to achieve a phase detector frequency of 20 MHz. A
very low integrated RMS jitter of 201 fs is measured vs. the 474 fs measured in
the Phase Noise section with 16 MHz crystal in the bandwidth of 10 Hz to 20
MHz.
10 Hz – 20 MHz integrated RMS jitter = 201 fs (shown)
100 Hz – 20 MHz integrated RMS jitter = 197 fs
1 kHz – 20 MHz integrated RMS jitter = 196 fs
12 kHz – 20 MHz integrated RMS jitter = 188 fs
Conclusion
This diagram illustrates how the phase noise inside the loop bandwidth is set by
the quality of the reference oscillator used. Phase noise outside the loop
bandwidth is set by the VCO noise level.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic."Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
