4. Usage
Connect a supply voltage (2.1 V up to 3.6 V) to the supply connector, according to the
indications on the board layout. For safety reasons, the maximum current is limited to
50 mA.
When a serial connection between the evaluation board and a PC is established, the
Windows software 'Frantic.exe' can be run. On start-up, the program initializes the special
function register set of OL2300 using the first available COM port. The communication
port used by the progam is shown in the left lower corner of the GUI. Each interaction with
the Windows program is immediately transferred to reflect the changes in the register set
of OL2300. The Windows program provides context-sensitive help.
A 50 spectrum analyzer is directly connected to X2. Ensure that the analyzer input
attenuator setting matches the RF output power level of the evaluation board using a
starting reference value of +20 dBm.

5. Measurement results
The evaluation board measurements are made under the following conditions, unless
otherwise stated:
• Supply voltage V
CC
= 2.7 V
• Power mode PAM = 3 with CASC = 0 and ENRAD = 0
• Output amplitude AMH = 15
• Temperature T = room temperature
• Carrier frequency f
C
= 433.92 MHz
Detailed measurements have been performed for the 434 MHz version of the evaluation
board only.
Measurement instruments:
• Spectrum Analyzer: Rohde & Schwarz FSP7
• Multimeter: Agilent 34401A
The following results indicate typical values only and vary as a result of device spreads,
component tolerances or temperature changes.
5.1 General
• Center frequency: 315 MHz
• Data rate: 4.8 kbps Manchester coded (symbol rate = 9600 chips/s)
• Modulation type: FSK
• Frequency deviation: 4.8 kHz
