SST Communications, a subsidiary of Silicon Storage Technology Inc. (SST) has launched its MelodyWing SP advanced wireless audio solution, which offers uncompressed, wire-equivalent sound quality for home theater surround sound and multiroom audio broadcasting found in many home entertainment applications including HDTVs, home theaters, STBs, headsets, game consoles, home gateways, multimedia PCs and audio streaming.

The MelodyWing SP is said to be the only wireless audio solution capable of supporting up to 24bits per channel for stereo (also compatible with 16bit stereo), 90dB dynamic range and IEC support for MP3, AAC, AC3 and DTS modes. The MelodyWing SP solution requires no firmware drivers or additional hardware for set-up. The embedded SuperFlash memory provides flexibility for system configuration and 48bit security code for privacy protection.

Wireless streaming
The MelodyWing SP solution enables each transmitter to wirelessly stream high-quality sound to two full-range speakers and a sub-woofer. The Smart Channel feature automatically selects the uncongested industrial, scientific and medical (ISM) radio bands at both 2.4GHz and 5GHz, to avoid interference with other wireless equipment and to enable pop-free sound effects.

The MelodyWing SP supports two standard digital audio interfaces, the Sony/Philips Digital Interface (S/PDIF) and I?S. Support for factory programmable worldwide ISM 2.4GHz and 5GHz radio bands (2.4GHz and 4.9-5.8GHz) and output power allows a single product design to meet the certification requirements of multiple markets, said the company.

As part of a wireless digital home entertainment system, the MelodyWing SP chipset can be configured in four solutions:

  • The Single Link wireless configuration mode allows a single wireless S/PDIF or 2.1 channel I?S connection between the audio source such as a digital TV, and a 2.1 multichannel speaker system comprised of a sub-woofer and left and right speakers with a wired connection to the sub-woofer.

  • The Triple Link wireless configuration mode allows three simultaneous wireless connections between the audio source and a 2.1 multichannel speaker system comprised of a sub-woofer and left and right channel speakers.

  • The Hextuple Link wireless configuration mode allows six simultaneous wireless connections between the audio source and a 5.1 multichannel speaker system comprised of a center speaker, a sub-woofer, left and right front speakers and left and right rear speakers.

  • The Multi Link wireless configuration mode allows multiple simultaneous wireless connections between the audio source and multiple 2.1 multichannel speaker systems located in multiple rooms.

20m and beyond
The physical distance supported is 20m for single-room applications. The distance supported for a Multi-Link solution can be further extended according to customer needs.

The MelodyWing SP wireless audio boards are comprised of the SST11SC03 transmitter board and the SST11SC04 receiver board. Pricing for the devices is $21.62 for the SST11SC03 and $21.62 for the SST11SC04, each in quantities of 10,000.

Evaluation kits are available.
