PRODUCTION DATA
The ADC32RF8x consumes approximately 6.6 W of power when both channels are active with a divide-by-4 complex output. When different DDC options are used, the power consumption on the DVDD supply changes by a small amount but remains unaffected on other supplies. In the applications requiring just one channel to be active, channel A must be chosen as the active channel and channel B can be powered down. Power consumption reduces to approximately 4 W in single-channel operation with a divide-by-4 option at a 2949.12-MSPS device clock rate.
Table 9-3 shows power consumption in different DDC modes for dual-channel and single-channel operation.
