PRODUCTION DATA
A key characteristic of CDR operation is the loop bandwidth. Input jitter at frequencies above the -3dB CDR loop bandwidth are attenuated by the CDR, while input jitter at frequencies below the -3dB CDR loop bandwidth are tracked but not attenuated at the CDR output. Depending on the input jitter present at the LMH12x9 input and application needs for the LMH12x9 output jitter, the CDR loop bandwidth can be adjusted.
The LMH12x9 features a highly configurable CDR loop bandwidth that can be controlled by either pin or register settings.
