Shenzhen, China - Oct 8, 2008 - Ibiquity Digital is offering its licensed HD Radio developers a reference platform for low-cost, low-power, battery-powered portable and USB-connected HD Radio products. Available for demonstration for the first time at the Hong Kong Electronics Show, the developers' package includes schematics, bill-of-material, layout and software.
This provides portable product manufacturers with a standard reference design to enable quicker time to market development. The reference platform is based on Samsung EM's Core-CR module measuring 20.0 x 13.0 x 2.3mm. The Core-CR module is a surface-mount device (SMD) package, which consists of a dual chip (RF -IF Peripheral and Baseband), dedicated memory SDRAM (64Mbit), and flash memory (8Mbit). The Samsung Core-CR Module has a total power consumption of 210mW and allows for 15 hours of continuous operation.
The portable HD Radio unit uses an Atmel AVR32 (AT32UC3A) as its host microprocessor. The portable reference platform has support for MP3, USB on-the-go, and an SD card interface. The reference has monochrome graphic LCD 128 x 64 and uses two AA alkaline batteries.
Ibiquity states that the USB design will greatly assist its partners in developing HD Radio data services and advanced visual-radio user interfaces. The USB reference design provides manufacturers with a path to add HD Radio technology to a PC, a portable navigation device or any device featuring a USB port.
The reference platform is capable of working with various new-generation radio modules (using Ibiquity's 2129 or 2023 interfaces). With the ability to accept two modules, the reference is suitable for developing products requiring a second tuner for data applications. The reference is provided in a hide-away-box form factor measuring 145 x 100 x 42mm and requires only USB and antenna connections.
The USB HD Radio reference design uses Atmel's AVR32 (AT32UC3B) as its slave microprocessor. Any attached USB host processor is able to receive audio and communicate with the reference platform over standard protocols (USB audio-class/USB HID-class), thereby requiring no proprietary drivers. In addition to USB audio, the reference design provides analog audio output and digital SPDIF output. The device can be powered by USB or an external supply.
