The CDCE72010 is designed as a high performance device, therefore careful attention must be paid to device

configuration with respect to power consumption. Total power consumption of the device can be estimated by

adding up the total power consumed by each block in the device.

The Table below describes the blocks used and power consumed per block. The total power of the device can

be calculated by multiplying the number of blocks used by the power consumption per block.
