1. 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. Table 1: Part Description BUFFER IC PACKAGE U1 LMK00101 LLP-32 2.
User’s Guide March 2012 2.1 Quick Start Description The LMK00101 EVK allows full verification of the device functionality and performance specifications. To quickly set up and operate the board with basic equipment, refer to the quick start procedure below and test setup shown in Figure 1. 1. Verify the output mode control switches, S1[1:4], match the states shown in Table 2 to reflect the default output clock interfaces configured on the EVK.
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 singleended clock. The three-input multiplexer is pin-controlled.
User’s Guide March 2012 An XTAL with the HC49 footprint can be populated on the bottom side of the PCB. Alternatively, a 3.2 x 2.5 mm XTAL can be populated on Y2, located on the top side. Only one XTAL footprint should be used at a time. The values of C42 and C25 (CEXT) depend on the load capacitance (CL) specified for the crystal. The OSC input capacitance (CIN) of the device is 1 pF differential, and the trace capacitance (CTRACE) of OSCin and OSCout is around 1 pF.
