Output Formatting with Decimation

When using decimation, the output data is formatted as shown in Figure 8-39 (complex decimation) and Figure 8-40 (real decimation).

Table 8-4 illustrates the output interface data rate along with the corresponding DCLK/DCLKIN and FCLK frequencies based on output resolution (R), number of SLVDS lanes (L) and complex decimation setting (N).

Furthermore the table shows an actual lane rate example for the 2-, 1- and 1/2-wire interface, 16-bit output resolution and complex decimation by 4.

Table 8-5 illustrates the output interface data rate along with the corresponding DCLK/DCLKIN and FCLK frequencies based on output resolution (R), number of SLVDS lanes (L) and real decimation setting (M).

Furthermore the table shows an actual lane rate example for the 2-, 1- and 1/2-wire interface, 16-bit output resolution and real decimation by 4.
