1. Introduction
OL2300 is a UHF ASK/FSK fractional-N transmitter IC. The device provides a fully
integrated fractional-N PLL frequency synthesizer and a power amplifier to drive an
external antenna.
The purpose of this manual is to provide an introduction to the evaluation board named
"LID1204", which is intended to evaluate the internal functional blocks of the OL2300..
The evaluation board is equipped with a serial RS232 interface to connect the board to a
PC. A Windows GUI provides a means to access the different special function registers of
OL2300. The onboard controller PCF7941 acts as a logical interface between RS232 and
OL2300 and it is programmed accordingly.
The power amplifier output of OL2300 is matched to 50 and can be directly connected
to appropriate measurement devices.
The evaluation board is available in two versions; one for the 315 MHz and one for the
434 MHz ISM frequency bands. Each version has a different mounting for the crystal and
different matching network of the 50 SMA connector output.
An 868 MHz version can be created by using the 434 MHz board, and changing some of
the component values (see Figure 1
).
Section 2 “
Evaluation board schematic” gives details of component placement, usage and
typical measurement results.

2. Evaluation board schematic
The schematic of the evaluation board is shown in Figure 1.
The 125 kHz transponder antenna of the PCF7941 and the three switches are not
mounted.
The transmitter section of the board is isolated by removing the following six jumpers:
TX_SUPPLY, EN, SCK, SDIO, CKOUT, SDO. The jumpers allow the following:
• evaluation of the onboard OL2300 IC in combination with another µC
• monitoring of the SPI connection
• current measurements
The crystal which is connected to the oscillator pins of OL2300 is an NDK NX5032GA. A
frequency of 13.28963 MHz is chosen to cover the 434 MHz band as well as the 868 MHz
and the 915 MHz bands. However, for the 868 MHz and 915 MHz band, the matching
network must be adapted accordingly.
In the 315 MHz version, the crystal frequency is 18.37036 MHz. The reference clock
frequency is divided by two to keep the PLL frequency below the specified maximum of
920 MHz. To achieve this frequency limitation, the internal XTAL clock divider is set to
XOSL = 1.
The UHF matching network is adapted to transform the 50 terminated output
impedance of connector X2 to the optimal impedance of the RF power amplifier. This is
done in a way to attain the highest possible output power in power mode III (PAM=3) with
a harmonic suppression of at least 50 dBc.

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

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.
