Programming Information
IDT82P2282
Bit Name
When LOS of the selected link is detected, the REFB_OUT pin outputs MCLK or high level, as selected by the REFH_LOS bit (b0, E1-03EH,...).
When LOS of the selected link is detected, the REFA_OUT pin outputs MCLK or high level, as selected by the REFH_LOS bit (b0, E1-03EH,...).
Default
Bit No.
Type
This bit selects the link to be internally looped to the REFB_OUT output pin:
= 0: The Link 1 is selected.
= 1: The Link 2 is selected.
When no LOS of the selected link is detected, the REFB_OUT pin outputs the recovered clock of the selected link from the Clock and Data
