11. Writing a New Frequency Plan or Device Configuration to Non-Volatile
Memory (OTP)
Note: Writing to the device non-volatile memory (OTP) is NOT the same as writing a configuration into the Si5342 using Clock-
BuilderPro on the Si5342 EVB. Writing a configuration into the EVB from ClockBuilderPro is done using Si5342 RAM
space and can be done virtually unlimited numbers of times. Writing to OTP is limited as described below.
Refer to the Si534x/8x Family Reference Manuals and device data sheets for information on how to write a
configuration to the EVB DUT’s non-volatile memory (OTP). The OTP can be programmed a maximum of two
times only. Care must be taken to ensure the configuration desired is valid when choosing to write to OTP.

Note: Please be aware that the Si5342-EVB schematic is in OrCad Capture hierarchical format and not in a typical “flat” sche-
matic format.
