Overview
ALIS V3 is a chip set used to connect analog phone lines to digital equipment such as fax machines. Its technology and design make it especially suitable for use throughout the world in:
• V.34 modems
• V.90 modems
• Fax machines
The ALIS V3 chip set is an ideal front end for modems and fax machines because these pieces of equipment have to convert digital information into analog signals and vice versa for communications via telephone lines. ALIS V3 bridges the gap between a digital data pump and an analog phone line.
FEATUREs
• The ALIS V3 chip set replaces the traditional Data Access Arrangement (DAA), codec and hybrid components.
• International features:
Programmable ring detection: international levels,
and frequency coefficients are downloadable
Caller ID: detection, decoding and storage is now
on-chip and programmable internationally
Programmable international DC characteristics
The ALIS V3 chip set complies with ETS 300 001,
TBR21 and FCC requirements.
• Modem features:
Programmable sampling rates in conformance with
V.34, plus future-proof 16 kHz and 32 kHz sampling
rates with one fixed master clock
High performance analog-to-digital and digital-to-analog conversion
Dual-line modem support
Voice modem with speaker phone and handset support
Output pin for line monitoring.
• Isolation by means of newly developed digital capacitor interface.
• Digital interface implemented with an interface processor; SIEMENS provides configuration support upon request.
• Analog part powered from the Tip/Ring line by an integrated voltage regulator.
• Wake-up function to support PC power management, different operating modes (sleep, conversation, ring) to cut power consumption to a minimum.
• Two-chip solution: the P-TSSOP24 and P-TSSOP28 package is PC Card compliant.
• General purpose I/O pins.
• 3 V technology
Output pins are TTL compatible
Input pins are 5 V tolerant.
