6.5.1 Data Rate and JESD Parameters

Data rates in the signal chain are often connected with the JESD mode (LMFS, SerDes rate), and a list of compatible modes are provided in the device data sheet. The following parameters in the basicbring-up.py script can be used to modify the configuration. Rerun the script after assigning new values to the following parameters.

## In below parameters, each element sets the particular LMFS-Hd for the particular channels.
# JESD and Serdes Parameters
sysParams.LMFSHdRx                = ["24410","24410","24410","24410"] 
sysParams.LMFSHdFb                = ["22210","22210"] 
sysParams.LMFSHdTx                = ["44210","44210","44210","44210"]
# Decimation and interpolation parameters for the data converter signal chains. 
sysParams.ddcFactorRx				= [12,12,12,12]
