Special precautions should be taken on both SD-Cx and SD-Dx signals to ensure a clean and noise-free signal that meets SDFM timing requirements. Precautions such as series termination resistors for ringing noise due to any impedance mismatch of clock driver and spacing of traces from other noisy signals are recommended.
The SDFM SD-Cx and SD-Dx signals, when synchronized to PLLRAWCLK, provide protection against SDFM module corruption due to occasional random noise glitches that may result in a false comparator trip and filter output. However, the signals do not provide protection against persistent violations of the above timing requirements. Timing violations will result in data corruption proportional to the number of bits which violate the requirements.
