5.2 PCIe Tool Input File Waveforms for the LMKDB1xxx Family

Figure 5-1 illustrates the output phase noise curve of the LMKDB1120 with a reference input of 100MHz, slew rate = 3.5V/ns, and peak-to-peak swing = 1.6Vpp. Figure 5-2 illustrates the output time domain trace waveform. All of these waveforms are inputted into TI's PCIe Compliance Tool (found within TI's TICS Pro Software, more information in Section 4) to determine PCIe compliance. These results and waveforms apply for all LMKDB1xxx devices.
