The LMK1C1108 is a high-performance, low additive jitter LVCMOS clock buffer with one LVCMOS input, eight
LVCMOS outputs, and a global output enable pin.
This evaluation module (EVM) is designed to demonstrate the electrical performance of the LMK1C1108.
Throughout this document, the acronym EVM and the phrases evaluation module and evaluation board are
synonymous with the LMK1C1108EVM.
The LMK1C1108EVM is equipped with 50-Ω SMA connectors and impedance-controlled 50-Ω microstrip
transmission lines for best performance.
