1.3
Satisfies Legacy Applications
The 536EPXX supports all PC-based communication requirements. Its robust host-based controller
software and powerful DSP support all standard AT commands for data, Class 1 fax and IS-101
voice.
1.4
Comprehensive Telephony Features
Voice telephony is becoming increasingly important. The 536EPXX offers a complete telephony
interface with Caller ID, voice mail, answering machine capabilities, tone generation and
detection, call progress control, telephone emulation and full-duplex digital speakerphone. All
voice features are fully compliant with Microsoft’s Unimodem V and TAPI standards, and all voice
commands comply with IS-101 voice command standards. Intel also provides DAA design
recommendations that support international telephony applications.
1.5
Reference Design Available
Intel provides a reference design that demonstrates chipset applications for several common
configurations. The design documentation includes a schematic (OrCAD), bill of materials, block
diagram and a description of operation.
1.6
Minimal Component Design
The 536EPXX was designed to reduce part count, board area and the amount of silicon used. These
design considerations significantly reduce the cost of the 536EPXX without sacrificing quality or
performance. The 536EPXX solution is a sleek, compact and cost effective alternative to both
software- and hardware-only modems.
1.7
Reduced EMI/RFI Emissions
A single low-frequency crystal serves as a clock for the DSP in the 536EPXX chipsets. The single-
crystal design minimizes high-frequency harmonics and simplifies EMI/RFI design considerations.
