CML Expands its PMR/LMR Product Line up with CML’s Sicomm Technologies

Maldon, Essex – 17 July, 2018 - CML Microcircuits is pleased to offer a new product from its Sicomm Technologies design centre. Strengthening CML’s presence in the Mobile Radio market, the SCT3258TD is a highly integrated baseband solution that includes both DMR and dPMR standards. As well as providing full support for the DMR and dPMR protocol stacks, the device is differentiated from CML’s other baseband processors by embedding multiple low rate vocoders including AMBE+2™ (Digital Voice Systems Inc.) and RALCWI (CML’s proprietary technology).

In its digital mode the SCT3258TD can sense the presence of analogue PMR and automatically switch operating mode. This enables radios containing the device to interoperate seamlessly with legacy radios, providing a smooth transition for users from analogue to the new digital standards.

David Brooke, CML’s Wireless Voice and Data Product Manager said, “We have been working closely with Sicomm to evolve their proven DMR and dPMR technology into ETSI compliant solutions. CML Microcircuits already has a selection of IC solutions for PMR and being able to offer the SCT3258TD further expands the range of baseband solutions available to our customers. CML now offers a choice of system architectures where the vocoder function is located in either the main microcontroller or on the baseband processor. Embedding and supporting multiple vocoders enable manufacturers to cost optimise designs, especially where standards do not dictate vocoder choice. This is a key factor in helping to close the cost differential between analogue and digital radios.”

CML works with radio manufacturers to ease the development process by providing in depth technical support and a hardware evaluation kit is available to assist in product evaluation.

CML China, trading as Sicomm Communication Technologies, is a professional IC design house located in Wuxi and Shanghai, China. Sicomm specialises in high quality, leading edge designs for digital voice radio, focusing on high volume, high integration and low cost digital voice radio solutions.

The SCT3258TD is available now through CML Microcircuits and its distributors.
