3.1 Introduction

The LMK6B is an ultra-high-performance clock oscillator using TI's BAW technology. The LMK6B is available in three package sizes: DLE (3.2mm × 2.5mm), DLF (2.5mm × 2.0mm), and DLR (2.0mm × 1.6mm). All three footprints are included on the EVM with independent termination networks. By default, the LMK6BEVM is populated with a 625MHz AC-LVPECL variant of LMK6B with a DLF package size (Y1). The DLE and DLR footprints are left unpopulated so the user can solder the desired frequency variant for evaluation.

The LMK6B is powered entirely using USB and the onboard voltage regulator. An external power supply can also be used for evaluation.

To begin evaluating the LMK6B BAW oscillator, use a matched pair of SMA coaxial cables to connect the clock output to test equipment such an oscilloscope or phase noise analyzer, or use the output directly as a clock source for another reference board.
