Hello
I want to make sure how much power will the AFE5809 comsume on such conditions:
sample clk: 20MSPS;
VCA low power mode;
decimation factor M = 32, 4 LVDS channels used;
input signal < 100mVpp.
I have tested it on the AFE5809EVM board.When it was in the M=4 I and Q Decimation test mode, and VCA in low power mode, the +5V current is 0.59A, which gave a 3.0W total board power consumption.When the chip was in a complete power down mode, the +5V current is 0.22A, which means that other elements on the EVM board would comsume a power of 1.1W. So is it right that the chip will consume about 1.9W power under my working condition? That much too higher than what it is in the data sheet (100mW/ch+55mW/ch)*8 @40MHz.
