PRODUCTION DATA
The strobe signal can also be output over all LVDS lanes. During transmission of the strobe, the entire sample is replaced by the strobe signal and therefore the sampled data are lost. When the strobe is disabled, all 12 bits of the digital sample are sent across the interface for full performance. The strobe can be enabled periodically to make sure synchronization is maintained only if loss of digital samples is allowed by the application. Enable this mode by setting SYNC_PAT in the PAT_SEL register to 0x3. Transmission of the strobe pattern is controlled by the source selected by SYNC_SEL in the LCTRL register. The SYNCSE pin controls transmission of the strobe pattern by default. Table 6-9 describes the strobe output when the strobe signal is output over all data pairs when SYNC is asserted. Table 6-10 describes the strobe output when the active pattern is used ( SYNC de-asserted).
