8.3.4.6.2 Serialized CMOS Interface

In serialized CMOS mode, the ADC3544 device supports complex decimation output Figure 8-32 and real decimation output Figure 8-33. The examples are shown for 16-bit output for 2-wire (8x serialization) and 1-wire (16x serialization).

GUID-1C2569D4-C605-4723-8C60-3BF158850256-low.gifFigure 8-32 Output Data Format in Complex Decimation

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 serial CMOS 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 16.
