2.2.5 EVM Quick Start Guide

The following guide allows the user to quickly configure the LMK3H0102EVM to evaluate the pre-programmed I2C or OTP configurations.

  1. If using software to program the device registers using I2C, install the TICS Pro software.

  2. Confirm the EVM default power configuration is set per Figure 3-2/Table 3-1 to power the LMK3H0102 using the on-board DC/DC converters with VDD = VDDO = 3.3 V.

  3. Set the control pin jumpers to select the desired start-up mode, as well as the other pin configuration settings, according to Table 3-2 for OTP Mode or Table 3-3 for I2C Mode. The default configuration is for I2C Mode.

    1. For OTP mode, Table 3-4 shows the default settings of the different OTP pages for the LMK3H0102V33 preprogrammed device configuration.

  4. Connect the micro-B USB cable to the micro-B USB port of the EVM, and connect the USB-A end to a PC.

  5. Observe any active clock on the OUT[1:0] SMA ports.

    1. OUT0 is AC-coupled, and OUT1 is DC-coupled.

    2. REF_CTRL is DC-coupled to the SMAs with a 33-Ω termination resistor in series.

    3. Use 50-Ω coax cables to connect the test equipment to the output SMA ports. If making a single-ended measurement on a differential output, terminate the unused SMA port with a 50-Ω load.

    4. To minimize output clock switching noise from affecting jitter-sensitive measurements, terminate any unused active output clock pair using 50-Ω SMA loads; otherwise, power-down unused output clocks via register programming.
