WARNING

The SDFM clock inputs (SDx_Cy pins) directly clock the SDFM module when there is no GPIO input synchronization. Any glitches or ringing noise on these inputs can corrupt the SDFM module operation. Special precautions should be taken on these signals to ensure a clean and noise-free signal that meets SDFM timing requirements. Precautions such as series termination for ringing due to any impedance mismatch of the clock driver and spacing of traces from other noisy signals are recommended.

WARNING

Mode 2 (Manchester Mode) is not recommended for new applications. See the "SDFM: Manchester Mode (Mode 2) Does Not Produce Correct Filter Results Under Several Conditions" advisory in the TMS320F2837xD Dual-Core MCUs Silicon Errata.
