Product Brief
ALIS V3
PSB 4595
PSB 4596
Analog Line Interface Solution
The ALIS V3 chipset is a complete, international
modem front-end, that integrates a fully program-
mable Data Access Arrangement (DAA) together
with a high quality codec.
The analog IC “ALIS-A” (PSB 4595)
contains the two-wire interface and
the codec. The digital device
”ALIS-D” (PSB 4596) incorporates
programmable digital filter structures
and a flexible data interface.
Capacitors across the digital con-
nection between the PSB 4595 and
the PSB 4596 provide line isolation.
The resulting advantages are:
s Significant cost savings
s International compliance
s System interface compatibility
s Best modem performance
s Shorter system development
and approval cycles
s Optimized solution for portable
and battery fed equipment
s PC 98 conformance
s PC-Card compliant form factor
Applications
s International Modems and Fax
s Host-based Modems
s PC-Card Modems
s Palmtop Computers
s Modem on Motherboard
s Embedded Modems
(e.g. Set-Top-Box)
Outstanding Features
s Reduced system cost
s Integrated two-wire line interface,
hybrid, codec, filters, ring detec-
tor, dialer, caller-ID decoder and
storage
s No transformer; few discrete
components. Reduced bill of
materials (BOM)
s Smaller PCB, faster assembly
s No need for country specific
designs and optimization
s No stuffing options required
s Reference approvals for fast,
successful homologations
s Acoustic line monitoring
s Voice codec interface
World-Wide Compliance
