LMK01000 EVM Operating Instructions

User's GuideSNAU037B–February 2008–Revised July 2019


1 OverviewThe LMK01000EVM is for the LMK01000 1.6 GHz High Performance Clock Buffer, Divider, andDistributer. The EVM can be used for device evaluation, compliance testing, and system prototyping.

2 Necessary Equipment• Power Supply:

– The Power Supply should be a low noise power supply. An Agilent 6623A Triple power supply withLC 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 theE5052A is superior for phase noise measurements. At frequencies less than 100 MHz the localoscillator noise of the PSA is too high and measurements will be of the local oscillator, not thedevice under test

• Oscilloscope:– The oscilloscope and probes should be capable of measuring the output frequencies of interest

when evaluating this board. The Agilent Infiniium DSO81204A was used in creating theseevaluation board instructions.

• 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 ~60 kHz. Inside the loopbandwidth of a PLL the noise is greatly affected by any noise on the reference oscillator (OSCin).Therefore any noise on the oscillator less than 60 kHz will be passed through and seen on theoutputs. For this reason the main output of a Signal Generator is not recommended for drivingOSCin in this setup.

3 Basic Operation• 1) Connect a low noise 3.3 V power supply to the Vcc connector located at the top left of the board.• 2) Connect 122.88 MHz signal from signal generator output to CLKin0 of board.• 3) Connect PC to the uWire header. For quick start on interfacing the board please see Section 5.

www.ti.com Quick Start for EVM communications




5 Quick Start for EVM communicationsTICS Pro is the software used to communicate with the EVM (Please download the latest version fromTI.com - http://www.ti.com/tool/TICSPRO-SW). This EVM can be controlled through the uWire interface onthe board using USB2ANY and an adapter board. Under "USB communications" → "interface" selectUSB2ANY.

Figure 8. USB2ANY-uWIRE Set up

Figure 9. USB2ANY-uWIRE Board Set Up

Alternatively if a USB2ANY-uWIRE board is not available the 10 pin connector can be spliced andconnected as shown in Figure 10, or jumpers can be used to connect USB2ANY directly to the EVM.Necessary connections include: GND, DATA, CLK, LE, GOE, and SYNC.
