PRODUCTION DATA
In parallel CMOS mode, the ADC364x device only supports real output with DDR CMOS interface as shown in Figure 8-37 (real decimation). Here the output format is selected to 14-bit since the parallel output bus only supports up to 14-bit.
Table 8-4 illustrates the output interface data rate along with the corresponding DCLK frequency based on real decimation setting (M).
Furthermore the table shows an actual lane rate example with complex decimation by 4.
REAL/COMPLEX DECIMATION | DECIMATION SETTING | ADC SAMPLING RATE | DDR CMOS | DCLK | DOUT |
---|---|---|---|---|---|
Real | M | FS | DDR | FS / M | FS x 2 / M |
4 | 65 MHz | DDR | 16.25 MHz | 32.5 MHz |
