SNLS545E March 2017 – July 2022 LMH1297
PRODUCTION DATA
The LMH1297 output function control for data routed to outputs SDI_IO (in CD mode), SDI_OUT, and OUT0 is configured by the OUT_CTRL pin. The OUT_CTRL pin determines whether to bypass the input equalizer, reclocker, or both. In normal operation (OUT_CTRL = F), both input equalizer and reclocker are enabled.
Table 8-7 lists the OUT_CTRL pin logic settings. These settings can be overridden through register control by applying the appropriate override bit values. For more information, refer to the LMH1297 Programming Guide.
