DESCRIPTION
The Le58083 Octal Low Voltage Subscriber Line Audio-
Processing Circuit (Octal SLAC™) devices integrate the key
functions of analog line cards into high-performance, very-
programmable, eight-channel codec-filter devices. The
Le58083 Octal SLAC devices are based on the proven design
of
Zarlink’s
reliable SLAC device families. The advanced
architecture of the Le58083 Octal SLAC devices implements
eight independent channels and employs digital filters to allow
software control of transmission, thus providing a cost-effective
solution for the audio-processing function of programmable line
cards. The Le58083 Octal SLAC devices are software and
coefficient compatible to the VE580 series QLSLAC™ devices.
Advanced submicron CMOS technology makes the Le58083
Octal SLAC devices economical, with both the functionality and
the low power consumption needed in line card designs to
maximize line card density at minimum cost. When used with
multiple
Zarlink
SLIC devices, an Le58083 Octal SLAC device
provides a complete software-configurable solution to the
BORSCHT functions.
