Si5338/Si5356 FIELD PROGRAMMING KIT USER’S GUIDE

Description

The Si5338/Si5356 Field Programming Kit provides all

of the tools necessary for writing a new configuration file

to the one-time programmable (OTP) non-volatile

memory (NVM) in the Si5338/Si5356 any-frequency,

any-output clock generator. This user ’s guide describes

the procedure for writing to the device NVM.

Field Programming Kit Features

Fully-powered from a single USB port

High-quality and easy-to-use socket

Simple software-based user interface

Status LEDs for Pass or Fail indication

1. Introduction

The Si5338/Si5356 is a highly-flexible and configurable clock generator/clock buffer. The device has a

factory-defined default configuration stored in non-volatile memory (NVM). During powerup, the default

configuration is copied into the random access memory (RAM). Having its working configuration stored in RAM

allows in-system configuration changes through the I2C port. During a power cycle, any configuration changes

stored in RAM are overwritten with the factory default configuration from the NVM.

The NVM is a one-time-programmable (OTP) memory that allows a user to define the default configuration. This is

a useful feature, especially if the Si5338/Si5356 is providing clocks to devices that require pre-defined clocks at

powerup. As its name implies, the OTP NVM can only be written once.

Figure 2. Memory Configuration

The field programming kit allows writing a new default configuration to the Si5338’s NVM memory. The kit consists

of the Field Programmer (Si5338-PROG-EVB), a USB cable, and the ClockBuilder™ Desktop Software. This

user’s guide outlines the steps necessary to write new default values to the NVM.

The NVM file must be created before writing it to the Si5338/Si5356. The NVM file is created using the

ClockBuilder Desktop, which is part of the ClockBuilder Desktop Software. NVM file support for the Si5356 is in

version 2.6 or later of the ClockBuilder Desktop Software. Version 2.5 or older only supports the Si5338. As

always, use the latest software version for best results. See "Appendix B—Installing the ClockBuilder Desktop

Software" on page 10 for installation instructions. Refer to the Si5338 or Si5356 user’s guides (available at

www.silabs.com) for information on using the ClockBuilder Desktop software.

3. Getting Started with the Si5338/Si5356 Field Programmer

(Si5338-PROG-EVB)

3.1. Installing the Software

Before connecting the Field Programmer (Si5338-PROG-EVB) to the host PC, the latest version of the

ClockBuilder Desktop Software must be installed. Refer to "Appendix B—Installing the ClockBuilder Desktop

Software" on page 10 for software installation instructions.

3.2. Connecting the Hardware

Connect a USB cable from the Si5338-PROG-EVB to the host PC. The Field Programmer is fully powered from the

USB port, so no other connections are necessary.

3.3. Running the Software

Once installed, run the Field Programmer software from the Windows Start menu.

Start Programs  Silicon Laboratories  ClockBuilder Desktop Software  Field Programmer

3.3.1. Settin g u p Commu ni ca ti o n

1. Select the desired t arge t device, Si5 356 or Si53 38. The one that is selected must be p laced in the socket when

it is time to program the NVM.

2. Before the software connects with the Field Programmer (Si5338-PROG-EVB), it automatically detects it s serial

number. If more than one field programmer is connected to the same PC, use the drop-down box to select one

of the field progr amm er s. Th is fe at ur e allo ws on e PC to co nt ro l seve ral fiel d pro gr amm e rs sim ultaneously.

3. All devices shipped from the factory are pre-programmed with an I2C address of 0x70. The field programmer

software will automatically use this I2C address when communicating with a device loaded into the socket. If the

device has a different I2C address, enter its new address in the box provided.

4. If the PC is connected to a valid field programmer, it will automatically select “Continue and connect to the

EVB”. If “Continue and do not connect to the EVB” is selected, the software could not find a valid field

programmer . Ensure that the field programmer (Si5338-PROG-EVB) is properly connected to the host PC using

a cable.

5. Click on OK.

4. Getting Ready to Write The NVM File

The NVM File contains all of the information needed to configure the NVM. Valid Register Map Files have a .nvm

extension and are created using the ClockBuilder Desktop software included in the Si5338-EVB or Si5356-EVB.

For more information about creating an NVM File, see the software User Guide available by clicking Help  Help

in any of the software.

4.1. Loading the NVM File

Click on the “Open Register Map File” button to select the desired .nvm file. The header of the register map file is

displayed in the File Header window if the software detects that it is a valid NVM file.

4.2. Load a Blank Device in the Socket

1. Before writing the NVM, a device must be loaded into the socket as shown below. Pull the lever to unlock the

lid. Ensure that there is not another device in the socket before proceeding. Note: Some field programming

kits are shipped with a plastic slug loaded in the socket. This plastic slug must be removed before

loading a device.

2. Insert a blank Si5338 or Si5356 device in the socket using a pair of tweezers or a suction tool. It is very

important that the Si5338 or Si5356 be inserted into the socket with the correct pin 1 orientation. Pin 1

on the device is marked with a white dot. Pin 1 on the socket is labeled on the PCB as shown below.

3. Once the device is properly loaded, close the lid. Ensure that the lid is fully closed and in the locked position.

5. Write to NVM

1. Click on the “Write NVM” button to make a final write to the one-time programmable NVM. Writing to the NVM

should only take a few seconds. When writing to the NVM is successful, the green LED will light. If there was an

error while writing to the NVM, the red LED will light. See the "Appendix A—Troubleshooting Guide" on page 9

to find the possible causes of an NVM failure.

2. Once the NVM is written, the device is ready for use.

3. Remove the device from the socket.

4. Load a new device into the socket.

5. Press the Write NVM button.

6. Repeat Steps 3 to 5.

APPENDIX A—TROUBLESHOOTING GUIDE

Use this guide to help troubles hoot possible source s of errors when an NVM write fails.

Writing to NVM Results in a “Fail” Status

Possible Causes

1. A device can only be programmed once. If the device loaded into the socket has already been programmed

(NVM was previously written), it cannot be re-programmed. This will cause a fail status. Load a blank device

into the socket.

2. Writing to NVM failed. The device may be defective and should be discarded. Load a new device into the

socket.

Writing to NVM Causes the “Busy” LED to Stay On

Possible Causes

1. The device loaded into the socket has incorrect polarity. Refer to “4.2. Load a Blank Device in the Socket” for

proper device orientation. Press the reset button on the Si5338-PROG-EVB; discard the device in the socket,

and load a blank device into the socket.

2. There is no device loaded in the socket. Press the reset button on the Si5338-PROG-EVB and load a blank

device into the socket.
