Introduction

The CC1000 single chip transceiver includes many features and great flexibility which makes
the chip suitable for a very large number of applications and system requirements. The
CC1000DK Development Kit is designed to make it very easy for the user to evaluate
transceiver performance and in short time develop his own applications.

The Development Kit includes two evaluation boards with a complete CC1000 transceiver,
voltage regulator and PC interface circuitry. Using the evaluation board connected to a PC
running the SmartRF
tested by keystrokes.

Technical features:

- RF power up to 10 mW (10 dBm) programmable in 1dB steps

-109 dBm sensitivity for 10

- Logic level data input/output (Manchester coded or NRZ)

- Logic level synchronisation clock output

- RSSI output

- 10.7 MHz IF output

The evaluation board includes a significant number of components for great flexibility.
However, only a minor part of these components are required in an actual application. Check
the datasheet for a typical application circuit.

Evaluation Board

The kit includes an Evaluation Board (CC1000EB) with the following items:

• A SmartRF

CC1000 chip.

• Necessary external surface mounted devices, SMDs, for the chip.

• Voltage regulator 4V-10V to 3V regulated voltage.

• Possibilities to apply a 3V voltage source directly (chosen by the switch on the board).

• Voltage-level interface circuits between the CC1000 chip (3V) and the parallel port of

the computer (5V).

• Connector for a PC parallel port cable.

• Connector for antenna, modulation data in/out, synchronisation clock out, RSSI out

and IF out.

• Edge connector for future use.

This board is designed with great flexibility so that you can evaluate the circuit performance
for several circuit configurations, and in development of your own applications. A layout
sketch of the evaluation board is shown in chapter 0.

The evaluation board is distributed in two versions, and the difference is the frequency band
of operation. The two versions are optimised for 434 MHz and 869 MHz to cover the two
licence free band in Europe. The operating frequency band is marked on the Evaluation
Board.

Description

The evaluation circuit board constitutes of three main parts. These are the RF-section, the
voltage supply and the PC-interface. The PC-interface contains voltage level shift circuit,
which buffers the control lines.

Voltage supply

You can chose between applying a 4-10V non-regulated supply voltage or a 3V regulated
supply voltage by setting a switch on the board (SPDT). If a non-regulated supply voltage is
applied, an on board regulator generates a regulated 3V supply. A diode prevents damage if
wrong polarity is used for the non-regulated input. The connector has five contacts, which is
shown below. In addition to the three supply voltage contacts, there are two contacts, which
can be used to measure the DC current to the CC1000 chip. A short jumper is placed
between these two contacts for the circuit to work. If you want to measure the DC current,
replace the jumper with an amperemeter (as shown in the figure below). The current range is
from 0 to 26 mA.

RF-section

The RF section consists of a CC1000 chip with external components. The different
components are explained below.

The loop filter

The CC1000 has integrated the loop-filter and shaping features on-chip. For flexibility it is
also possible to use an external loop-filter. The PLL loop filter contains the components
C121-C122 and R121. However, in most cases the internal filter will give the optimum
performance. The loop filter is connected to the same pin as the monitoring of the lock
indicator (see 2.1.4). When external loop-filter is added, the R122 must be removed to avoid
conflict with the lock line connected to the parallel port.

The LOCK signal

A LOCK signal is connected to the parallel port interface to be monitored by the software. The
signal tells you if the synthesiser frequency is in lock. It is also available at a test pin, TP2,
and is active high.

This digital output can also be configured to other functions, as control signal for external PA
or external LNA. Please see the data sheet for details.

Note: To monitor this signal CC1000 must be configured to take out this signal on CHP_OUT.
This is the default setting of SmartRF

®

Studio. If external loop filter is added the lock signal

can not be used due to the loop filter is connected to the same pin.

DIO and DCLK

The modulation input/output (DIO) and the synchronisation output (DCLK) is connected to
separate connectors. The connectors are of SMA female type. The data to be sent can be of
either Manchester or NRZ. The Manchester code ensures that the signal has no DC
component. The Manchester code is based on transitions; a “0” is encoded as a low-to-high
transition, a “1” is encoded as a high-to-low transition. See figure below. Maximum data-rate
is 9.6 kbit/s giving a baud rate of 19.2 kbaud that is chosen in the software. For NRZ the baud
rate is equal to the bit rate and is maximum 19.2 kbaud.

To test your module use a 3V

logic level with 1-10 kHz square wave for Manchester coded

pp

data and 1- 20 kHz square wave for NRZ data.

The CC1000 has an internal clock synchronisation circuit that can be monitored on DCLK.
The relationship between DIO and DCLK is given below, for the different modes of C1000.
Please see datasheet for details.
