dspblok 21569 + USB Audio Class II - Analog Devices ADSP-21569 UAC2 SHARC DSP Module

The dspblok™ 21569uac2 combines a powerful floating-point DSP with a dedicated USB Audio Class 2 coprocessor.

An Analog Devices ADSP-21569 SHARC DSP operating at 1 GHz and an XMOS XU208 providing the USB audio support are the heart of the module.

The module includes flash, EEProm, SDRAM, 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.

Development couldn't be easier. The dspblok 21569uac2 is supported by Analog Devices 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 21569uac2 is available as a sub-component in other Danville products such as the dspNexus family. In this system, the dspblok is graphically programmed via DSP Concepts Audio Weaver.
