8.3.10.2 CD_N (Carrier Detect)

The LOCK_N pin can be reconfigured through register control to indicate a CD_N (carrier detect) event. When configured as a CD_N output, the pin asserts low at the end of adaptation after a valid signal is detected by the carrier detect circuit of the selected input. Under register control, this pin can be reconfigured to indicate CD_N for SDI_IO (in EQ Mode) or IN0 (in CD Mode). For more information about how to configure the LOCK_N pin for CD_N functionality, refer to the LMH0397 Programming Guide (SNLU225).
