Si468X EVALUATION BOARD TEST PROCEDURE

1. Introduction

The purpose of this document is to describe the test procedures used in Silicon Laboratories for the Si468x

evaluation boards (EVB). It is also intended to enable customers to exactly replicate Silicon Laboratories’ test

environment so that variances in customers’ and Silicon Laboratories’ measured results can be accurately

compared. This document covers FM, FMHD radio, and DAB/DAB+ radio tests for the Si468x receivers and FM

HD demodulators. The pass/fail criteria for each test are provided in the respective data sheets.

The Si468x evaluation boards and software provide a platform to program, test, and operate the Si468x devices.

The system consists of two boards: a baseboard and an RF daughter card. The baseboard provides all necessary

support functions, including a USB-based programming interface, audio output connection points and an optional

external clock input. In addition, the baseboard provides a codec for converting analog audio output to I S digital

output. The RF daughter card contains the receiver and connection points for RF input. Refer to the EVB User’s

Guides for detailed explanations of the EVB hardware and software. Table 1 summarizes the functionality of each

device in the family.
