5.2.3.4Analog Anti-Aliasing Low Pass Filter

The 5th order equal-ripple analog filter provides filtering of the analog signal from AGC before it’s being converted to digital signal with the ADC. Its main function is to avoid aliasing for the ADC circuit.

5.2.3.5Analog to Digital Converter (ADC) and FIR

The output of the analog filter is quantified using a 6 bit FLASH ADC. The digitized data is then equalized by the FIR to the NPV target response for Viterbi detection. The FIR filter consists of 10 independent programmable taps.
