2.2 Power Supply
Apply 3.3 V to the J9 header. The acceptable supply voltage range is 3.2 V to 3.4 V. The maximum current
consumption in the most extreme configuration must not exceed 100 mA.
2.3 Reference Clock
Connect OSCINP SMA connector with one of the outputs from Reference PRO. The EVM is configured for
single-ended input with OSCIN_P pin connected to OSCINP SMA connector and OSCIN_N pin floating. If
required, the EVM can be modified to operate with different clock source in different configuration, see
for details.
Terminate the unused output of the Reference PRO board with a 50-Ω resistor or SMA load. By default, the
output clock from Reference PRO is a 100-MHz LVPECL clock.
has the details of Reference PRO.
2.4 RF Output
Connect RFOUTRX SMA connector to a signal analyzer. Output frequency is 480 MHz and the amplitude is
about +1 dBm.
By default the evaluation software, TICS Pro, has RFOUTTX power down. This SMA connectors could be left
open.
2.5 Programming
Connect ribbon cable from Reference PRO to LMX2571EPEVM.
Connect USB cable from a PC to USB port in Reference PRO. This provides power supply to Reference PRO
board and communication with TICS Pro. A firmware update may be required, see
for details.
2.6 Evaluation Software
Download and install TICS Pro to a PC. Run the software and follow the following steps to get started.
