PR Description

This PR updates the AD9545 with the following:

  • Corrects a logic issue with how the slew rate limit was being set

  • Bug fix (a change that fixes an issue)
  • New feature (a change that adds new functionality)
  • Breaking change (a change that affects other repos or cause CIs to fail)

PR Checklist

1aa80a1 
Corrects a logic error when writing the slew rate limit value for
the PLLs.  Condition block incorrectly checked for a 0 value,
rather than a non-zero.
