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 3.5 W in single-channel operation with a 12-bit, 2.6-GSPS output (bypass mode). Table 120 shows power consumption in different DDC modes for dual-channel and single-channel operation. Table 120.
