1. General Description
This user guide describes how to set up and operate the LMK00308 evaluation module (EVM). The
LMK00308 is a 3-GHz, 8-output differential clock buffer intended for high frequency, low additive jitter clock
distribution and level translation. The EVM allows the user to verify the functionality and performance
specifications of the device. Refer to the LMK00308 datasheet for the functional description and
specifications.
2. Features
Low-noise clock fan-out via two banks of four differential outputs and one LVCMOS output
Selectable differential output type (LVPECL, LVDS, HCSL, or Hi-Z)
3:1 input multiplexer with two universal input buffers and one crystal oscillator interface
DIP switch control of device configuration
3.3 V core and 3 independent 3.3 V/2.5 V output supplies (one per output bank) using external supply
inputs or optional LP3878-ADJ LDO or LMZ10500 switching regulator on board
AC- or DC-coupled input & output interface with low-skew, controlled-impedance traces and edge SMA
connectors
