GENERAL DESCRIPTION
The Am79Q061/063 Quad Subscriber Line Audio-
Processing Circuit (QSLAC) devices integrate the key
functions of analog linecards into high-performance,
very-programmable, four-channel codec-filter devices.
The QSLAC devices are based on the proven design of
Legerity’s reliable SLAC device families. The
advanced architecture of the QSLAC devices
implements four 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 linecards.
Submicron CMOS technology makes the Am79Q061/
063 QSLAC device economical, with the functionality
and low power consumption needed in linecard design,
maximizing density at minimum cost. When used with
four Legerity SLICs, a QSLAC device provides a
complete software-configurable solution to the
BORSCHT function.
The Am79Q061/063 device supports the feature set of
the Am79Q02/021/031 device and provides a General
Circuit Interface as a programmable option.
