• Manufacturer: Silicon Laboratories

Si5338
2.19. Field/Factory Programming Options
The Si5338 any-rate clock generator supports a
customer-accessible one-time programmable NVM for
field programming. This optional feature allows users to
specify the startup configuration of the device. Following
device programming and a subsequent POR, the device
will come up in this new default configuration. This
feature is available through the customer programming
kit (Si5338-PROG-EVB) and the Si5338 configuration
software. Once the default profile is written, it cannot be
changed. Note that the device supply voltage must be
set to 3.6 V during a NVM write.
2.19.1. Si5338 Programmable Default Configuration
The Si5338 configuration software can be used to order
factory-programmed Si5338 clock generators with user-
specified startup configurations. The output of the
Si5338 software is a device configuration file. This file
can be sent to Silicon Labs and a unique Si5338 part
