Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control
systems, or other applications whose failure can be reasonably expected to result in serious physical and/or
material damage. Consult with your SANYO representative nearest you before using any SANYO products
described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that exceed,
even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters)
listed in products specifications of any and all SANYO products described or contained herein.
Overview
The LC82161B-E is a special-purpose processor for VoIP
communication equipment such as IP telephones. It
integrates the ARM7TDMI-S
TM CPU core, an audio signal
processing DSP (FAVOR40), and two 10/100 Base
Ethernet MACs on a single chip.
The LC82161B minimizes audio quality degradation using
a Sanyo-developed jitter buffer control algorithm that runs
on the DSP. Furthermore, this IC's protocol engine
hardware
processing
reduces
the
network
protocol
processing load on the CPU.
