  • Page 3: Introduction

    Introduction The CC2420 is a true single-chip 2.4 GHz IEEE 802.15.4 compliant RF transceiver designed for low-power and low-voltage wireless applications. The CC2420DK development kit is a powerful and flexible tool specifically designed to make it easy for the user to evaluate the RF performance of the CC2420 and to minimize the time spent on evaluation.

  • Page 4: Cc2420 Evaluation Module

    CC2420 Evaluation Module The CC2420EM Evaluation Module contains the CC2420 chip together with the external circuitry needed for proper operation. Not all components are needed in an actual application. Please see the data sheet for a typical application circuit. The CC2420 operates in the 2.4 GHz frequency band. Although this frequency band is usually described as “world-wide”, some countries do not allow unlicensed operation in this band.

    Jumpers Name Default setting Description Between pins Determines how the I/O supply of the CC2420 is supplied 6 and 8 with power. If the jumper is connected between pins 8 and 6, the 1.8V supply is used. If the jumper is connected between pins 8 and 10, the 3.3V supply is used.

  • Page 14: Connectors

    Connectors The Evaluation Board is furnished with many connectors for easy access to various signals. Test Port 1 (P17) and Test Port 2 (P5) are 2x10 pin pin-row connectors that are connected to the FPGA and can be used to monitor various signals, including all the CC2420 signals. The pin-out of these connectors is compatible with logic analyzer probes from Agilent.

  • Page 15: Pcb Layout, Cc2400Eb

    PCB layout, CC2400EB The Evaluation Board is a 4-layer, 1.6 mm thick FR-4 PCB. Four layers are used because of the routing requirements. Layers 1 and 4 are used for signal routing, layer 2 is a ground plane and layer 3 is used for power routing. The majority of the components are mounted on the top side of the PCB, while a few decoupling capacitors were put on the bottom side.
