    Introduction This user guide describes how to set up and operate the LMK00101 evaluation board kit (EVK). The LMK00101 is a high performance, low noise, low voltage CMOS fanout buffer. The core voltage can be 2.5 or 3.3 volts, while the power supply for the outputs can be selected from: 1.5 V, 1.8 V, 2.5 V, or 3.3 V, provided that it does not exceed the core supply voltage .
  • Page 3 Signal Path and Control Switches The LMK00101 supports single-ended or differential clocks on CLKin0 and CLKin1. A third input, OSCin, has an integrated crystal oscillator interface that supports a fundamental mode, AT-cut crystal or an external single-ended clock.
  • Page 4 Best performance is achieved with DC-coupled differential input clock. Crystal Oscillator Interface The LMK00101 has an integrated crystal oscillator interface (OSCin/OSCout) that supports a fundamental mode, AT-cut crystal. If the crystal input is selected, an optional onboard crystal on either footprint Y1 or Y2 will start-up and the oscillator clock can be measured on any enabled output.
