Merging AES67 RAVENNA Linux driver for ADI ADSP-SC573

Merging Technologies, and Analog Devices, Inc. (ADI) are partnering for an embedded solution for ADI’s ADSP-SC57x SHARC audio digital signal processors (DSPs). As an asset of this new partnership, a much broader audience will be able to access this state-of-the-art AES67 technology and enable OEMs to design for AES67 using the ADI ADSP-SC573.

This solution will give a lot of key features for manufacturers of electronics who want to go the AES67 route.

Features

  • Merging Technologies’ experience in the AoIP field (RAVENNA/AES67)
  • The ADSP-SC573 is a high-performance, power-efficient, real-time platform that delivers greater than 6 giga-floating-point operations per second using two enhanced SHARC+ cores and advanced DSP accelerators.
  • Up to 8 channels of audio (8 in + 8 out) at 44.1/48kHz and 4 channels of audio (4 in + 4 out) at 88.2/96 kHz.
  • Perfect for FIR
  • ARM processor and especially from 2 Sharc DSPs to carry out digital audio processing.
  • Cost efficient licensing. Only pay for the channels needed, no additional licensing fees.
  • The perfect solution for loudspeakers of any type or smaller Audio interfaces.
