JAJSEY1C April 2019 – March 2022 ADC12DJ5200RF
When the ADC is operating in single channel mode (based on the JMODE setting) then the PFIR filter can be set in single channel equalization mode. This mode allows frequency equalization of the ADC. The filter consists of 9 coefficients that can be independently set. The center tap of the 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 single channel equalization is shown in Figure 7-5.
