noise. The receive link is constrained to be within 100 ppm of eight times the
REFCLK frequency.
As shown in Fig. 5, two datapath loopbacks are provided on each LVDS link to
aid in fault isolation and continuity verification. The metallic loopback routes
receive data to the transmitter. The diagnostic loopback replaces the receive
data with the transmit data. The two loopbacks can be enabled individually or
simultaneously on the same link, and each link can be looped back
independently of the other seven.
