The dspblok™ 21479u8a combines a powerful floating point DSP with a dedicated USB Audio Class 2 coprocessor.

An Analog Devices ADSP-21479 SHARC DSP operating at 250 MHz and an XMOS XS1-U8A providing the USB audio support are the heart of the module.

The module includes flash, EEProm, and switching power supplies to support the core voltage requirements. All the connections are brought out to standard 2mm dual row header footprints. The board is only 60mm x 60mm (2.36" x 2.36").

USB Audio Class 2 is supported by Danville supplied Microsoft Windows drivers along with native support in Apple and Linux operating systems. In addition to the USB Audio Class 2 support, Danville has enhanced the USB firmware to include HID endpoints for control. This allows DSP code to be uploaded without a programmer or ICE as well as support for graphical design programs like DSP Concepts Audio Weaver.

The dspblok 21479u8a is particularly well suited for low power applications. The USB port can operate independently to support USB bus powered enumeration requirements.

The dspblok 21479u8a is the low power version of our fourth generation SHARC based Audio dspbloks. It is compatible with other fourth generation dspbloks engines such as our dspblok 21489uac2 and dspblok 21469uac2. These dspbloks are recommended for self powered applications since they have more computation power at the cost of higher power consumption.

Development couldn't be easier. The dspblok 21479u8a is supported by Analog Devices’ Visual DSP++ or CrossCore Embedded Studio. You can connect to an Analog Devices ICE-1000 or ICE-2000 via JTAG. Our dspblok dev board is a convenient way to get started with breakouts interfacing to your own external circuits.

Alternatively, the dspblok 21479u8a is available as a sub-component in other Danville products such as the dspMusik 2/8. In this system, the dspblok is graphically programmed via DSP Concepts Audio Weaver.
