Loopback Operation
Each lane of the PI2EQX5804C provides a loopback mode for test purposes which is controlled by a strapping
pin and I
abled. When LB# is low the loopback mode is enabled. The fi gure below diagrams this operation. Loopback
is not intended to be dynamically switched, and the normal system application is to initialize to one confi gura-
tion or the other.
The Loopback mode can also support mux/demux operation. Using I
puts can be disabled to minimize power and unnecessary noise.
