1. Introduction
Thank you for purchasing the Silicon Laboratories Inc. Si471x FM Transmitter Evaluation Board (EVB). This EVB
and associated software has been designed to speed the overall development process and decrease the required
development time from EVB to product launch. We are looking forward to working with you, and have posted
support articles, answers to frequently asked questions, and application notes at www.mysilabs.com.
The Si471x EVB kit should include the following important items:
Si471x FM Transmitter customer welcome and evaluation letter
Si471x EVB baseboard Revision 1.3 (Firmware 1.B)
Si471x daughter card Rev 1.2 with Si471x chip pre-mounted

2. Overview
The Si471x Evaluation Kit includes an evaluation board (EVB) to facilitate evaluation of the Si471x using the
associated software. The EVB consists of a baseboard with a pre-mounted daughter card—Si471x is pre-installed
on the daughter card. The Si471x comes in a 3 x 3 mm 20-pin QFN package. Several input/output (I/O)
connections provide access to the various subsystems on the EVB. Refer to Figure 1 for the location of the various
I/O connectors/devices.
The Si471x family includes:
Si4710 - FM Transmitter
Si4711 - FM Transmitter with RDS
Si4712 - FM Transmitter with Received Power Scan (RPS)
Si4713 - FM Transmitter with RDS and RPS
This Firmware 1.B release supports Si471x with RDS and limiter as the new feature. On the Si47xx GUI itself, it
exposes the overmodulation, loud detection, and silence detection features that have been available from the
previous release.
This document references the Si471x data sheet.
Note: The Si471x Firmware 1.B uses library R4, which is not backwards compatible with the Si471x part that uses library R1
(e.g. Alpha 0, Alpha 1, Alpha 2, and Alpha 3).
3. Description
The following sections refer to both the image in Figure 1 and the silkscreen on the Si471x EVB. It is
recommended to refer to both when using this guide.
