CLRC663 Quickstart Guide

1. Introduction

This document describes the basic requirements to power up the reader IC. This

application note does not replace the CLRC663 datasheet. Please refer to the datasheet

to read more information on each chapter. This document also gives an overview of the

RC663 evaluation reader board and describes the function and first steps of using the

board and the RC663. For this Application Note Version 3.0 of the 663 reader board is

used.

2. General description of the RC663

The RC663’s overall functionality can be separated into three functions:

1. Generate the RF field: The generated magnetic field has to be maximized within the

limits of the transmitter supply current, general emission limits and requirements to

protocol standards.

2. Transmit data: The coded and modulated data signal has to be transmitted in a way,

that all supported card standards are able to receive it. The signal shape and timing

according to relevant standards has to be considered.

3. Receive data: The response of a card or NFC passive device has to be transferred

to the differential or single sided receive input of the RC663 considering various

limits, e.g. maximum voltage and receiver sensitivity.

In the following chapters the general wiring just like the power supply concept, interface

selection and so on is described.
