Block diagrams
SCT3288 is a low power, high performance baseband processor supporting the dPMR and DMR protocols. With an internal codec (audio band ADC and DAC), it completes the entire physical layer and data link layer, and most of the call control layer processing of dPMR and DMR protocols. In dPMR mode it complies with ETSI TS 102 490 and ETSI TS 102 658; in DMR mode it complies with ETSI TS 102 361.
