Product description

The SCT3268TD is a highly integrated,  low power, high performance, Digital/Analog PMR/LMR baseband processor with an embedded vocoder and ARM 32-bit Cortex-M0 host microcontroller.

The SCT3268TD is available from CML’s ‘Sicomm Technologies’ product range that is specifically targeted at high volume and low cost radio applications.

The SCT3268TD includes the entire physical layer, data link layer and much of the call control layer processing of the digital PMR/LMR radio protocols.  Combined with a suitable RF front end, external audio codec and host controller, a complete digital radio that also supports analog mode can be developed in a short time frame.

The Design Reference SCT9389 provides a an easy route to developing a 2W multi-mode DMR/dPMR/Analog radio.

Detailed product support is available including an evaluation kit, application notes, FAQs and reference design material.
