7.3.5 Input-Output Mux Selection

By default, the LMH1219 input-to-output signal flow and data rate selection are configured by the IN_OUT_SEL pin logic settings shown in Table 2. These settings can be overridden via register control by applying the appropriate override bit values. For more information, refer to the LMH1219 Register Map and Programming Guide.

Table 2. IN_OUT_SEL Pin Settings
