The Digital Voice Systems, Inc. (DVSI) AMBE-20x0™ HDK is a multipurpose
vocoder development tool and reference design based on DVSI's AMBE-
2000™ / AMBE-2020™ Vocoder Chips. The AMBE-20x0™ HDK is ideal for
evaluation and test of vocoder performance and capabilities. The AMBE-
20x0™ HDK provides a comprehensive, evaluation, test and development
platform that helps product designers and manufacturing engineers gain
experience with low-bit-rate vocoders. This valuable knowledge enables them
to efficiently design and quickly produce high performance, narrowband
communication equipment. This results in lower development costs and faster
time to market.
The AMBE-20x0™ HDK employs DVSI's successful full-duplex AMBE-2000™
vocoder chip. This chip as well as the AMBE-2020™ (half-duplex version)
are currently used in an endless array of digital communication systems around
the globe. Both chips implement DVSI's patented AMBE
Technology to provide exceptional voice quality even at low data rates. These
vocoder chips are an affordable and power efficient voice compression solution
that support compression bit rates from 2000 to 9600 bps.
Both chips include Forward Error Correction (FEC) to optimize robustness to
background noise and channel bit errors. This level of performance has
resulted in the successful deployment of wireless communication systems in
the most demanding environments. Also, the AMBE-2000™ and the AMBE-
2020™ vocoder chips include a number of advanced features such as: Voice
Activity Detection (VAD), adaptive Comfort Noise Insertion (CNI) and support
for DTMF tones.
