The LMK04368EP EVM 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 2-1.
- Connect a voltage of 4.5 V to the VCC
SMA connector or terminal block. The LMK04368-EP and onboard VCXO operate at 3.3
V provided by the onboard TPS7A4701-EP LDO and LP5900 LDO, respectively.
- Connect a reference clock to the CLKin1* port
from a signal generator or other source. Use 122.88 MHz for the default
configuration.
- Connect a USB Cable A Plug to Micro B Plug cable
to a PC and the USB connector (J45) at EVM.
