DSP Group’s DHAN-M module is based on the state-of-the-art DCX81, a second-generation DECT SoC. The DHAN-M module is designed for DECT-ULE applications that employ a processor external to the DHAN-M. The DHAN-M can serve as a DECT-ULE hub (=base station) when loaded with a CMBS software image. This image includes standard DECT-ULE MAC-PHY connectivity as well as CAT-IQ functionality for traditional DECT telephony and HAN-FUN (ULE Alliance Standard) functionality for ULE (low-power packet mode). The DHAN-M interfaces with the host processor via UART or USB; different part numbers designate the chosen interface. Audio is transferred either via TDM (with control via UART) or via USB (Audio Class).
The DHAN-M can also be loaded with a software image that empowers the module with a DECT “handset” profile (CMHS). 1.2.
Features include excellent radio performance, with over 123dB system gain; a printed antenna in the module (a second antenna port is provided and can be routed to an optional diversity antenna located elsewhere in the application housing); the radio covers all regional DECT bands, only a simple re-configuration of the EEPROM is required; the Radio is fully compliant with ETSI DECT and ULE standards, regulatory (EU, FCC) certification is pending; compact, measuring only 27.2×15.2×3.3 mm (including the RF shield height); operating temperature range spanning -40˚C to 85˚C.
