LMK6x Evaluation Module
Description
The LMK6x evaluation module (EVM) is a platform
for evaluating the performance of the LMK6x family
of high-performance bulk acoustic wave (BAW)
oscillators. BAW is a microresonator technology that
enables the integration of high-precision and ultra-low
jitter clocks directly into packages that contain other
circuits.
