Pairing of audio analyzer and protocol analyzer streamlines closed-loop audio measurement of SoundWire-enabled devices
BEAVERTON, OREGON, September 13, 2016: Audio Precision, the recognized standard in audio test, today announced its collaboration with LnK to address the SoundWire audio test needs of MIPI Alliance member companies. Combining an APx Series audio analyzer with LnK’s protocol analyzer creates a closed-loop measurement system for the real-time evaluation of chipset and mobile product designs incorporating MIPI’s SoundWire interface.
Developed to address the limitations—such as power, pin count, ease-of-integration, scalability—of legacy interface designs, MIPI SoundWire reflects the efforts of more than 25 MIPI Alliance members and offers both complementary and unique features as an alternative to MIPI SLIMbus® for the integration of audio devices in mobile, or mobile-inspired, systems. SoundWire can be implemented in small, very cost-sensitive audio peripherals such as amplifiers and microphones and offers features that include double data rate; low complexity, power and latency; PCM and PDM formats; and multichannel data.
Closed-Loop SoundWire Audio Test
The pairing of an APx Series audio analyzer and LnK protocol analyzer eliminates the need for device designers to develop their own SoundWire Master IP in order to conduct audio testing. More importantly, it offers additional, real-time test capabilities, including the measurement of propagation delay, acoustic response and other transient behaviors. Audio Precision and LnK will demonstrate SoundWire audio testing at this week’s MIPI Development Conference (booth #8) in Mountain View, California, USA.
“We’re excited to collaborate with LnK and streamline the audio test of SoundWire devices” said Spyros Lazaris, Audio Precision Vice President of Sales and Marketing. “And helping engineers, in this case mobile chipset and product designers, as they endeavor to develop and verify the performance of their next-generation systems is at the core of what we do.”
Founded in 2007, LnK provides protocol analyzers, as well as training and test consulting services, for SLIMbus and SoundWire interface technologies. LnK is an active member of the MIPI Alliance. For more information, visit http://www.lnk-tools.com/.
