8.3.4.7 Output Formatting with Decimation

When using decimation, the output data is formatted as shown in Figure 8-32 and Figure 8-33. The examples are shown for 16-bit output for 2-wire (8x serialization), 1-wire (16x serialization) and 1/2-wire (32x serialization).

Table 8-3 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.
