PRODUCTION DATA
When the ADC is operating in dual channel mode (based on the JMODE setting) then the PFIR filter can be set in dual channel equalization mode. This mode allows independent frequency equalization of the two ADC channels. The filter for each channel consists of 9 coefficients that can be independently set. The center tap for each filter has a resolution of 18 bits and the LSB has a weight of 2-16. The non-center taps have a resolution of 12-bits with programmable LSB weight of 2-10, 2-11, 2-12, 2-13, 2-14, 2-15 or 2-16. All non-center taps have the same LSB weight. The block diagram for dual channel equalization is shown in Figure 7-4.
