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 2 configuration changes through the I C 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.

Memory Configuration The field programming kit allows writing a new default configuration to the Si5338s NVM memory. The kit consists of the Field Programmer (Si5338-PROG-EVB) and a USB cable. This users guide outlines the steps necessary to write new default values to the NVM. The NVM file must be created in ClockBuilder Pro before writing it to the Si5338/Si5356. NVM file support for the Si5338 and Si5356 is included in version 2.36 or later of the ClockBuilder Pro Software. 2 Skyworks Solutions, Inc.
