Frontier Silicon shrinks miniaturised DAB+ module
Frontier Silicon has produced its smallest module to date for DAB+ (digital audio broadcast plus) radios. The Siena module measures 21 x 21mm and is a low power, cost-optimised module, designed for both entry-level price-point DAB+ radios, and consumer audio devices which offer DAB radio as one of several functions.
Siena is based on Frontier Silicon’s Kino 4-Lite silicon, a single integrated chip, which combines a multi-band RF tuner, digital baseband, and application processor. Using surface mount technology (SMT), the module can be fixed directly to a DAB radio system board without the need to include a connector.
Siena also introduces technologies to optimise power consumption, RF and audio performance, says Frontier Silicon. The Siena module – with its smaller footprint, reduced power consumption and lower cost – will address this segment and help drive market growth, promises the company.
For entry price-point devices, Siena operates as the master processor. For customer audio systems, the module can be incorporated as a slave digital radio system driven by a host microcontroller unit (MCU).
Frontier Silicon specialises in technology for digital radio and smart audio products. Frontier Silicon’s audio products target DAB/DAB+, Internet Radio and Wi-Fi-enabled wireless speakers and soundbars – from silicon through software to production-ready platform designs.
