Overview
The analog modem was designed to operate with any dial-up phone,
worldwide. These modems support high-speed analog data, voice, and
fax operation. The integrated modem is host controlled which reduces
the overall chip count and need for a separate microcontroller.
The V.90-enabled analog modem supports data speeds up to 56 Kbps
from a digitally connected central site modem. The modem is ideal
for remote access applications such as ISP, online service, or corporate
site. Data can be sent upstream at speeds up to 33.6 Kbps. As a
V.34 data modem, the modem operates at line speeds up to 33.6 Kbps,
provides error correction and data compression, maximizes data transfer
integrity, and boosts average data throughput to 115.2 Kbps.
Market Research
An analysis by IDC predicts the worldwide analog modem shipments
to grow from 76 million units in 2000 to 95.4 million units in 2002
and up to 115 million units in 2004. However, the worldwide installed
base of analog modems from the total Internet connectivity methods
is shrinking from 79.5% in 2000 to 66.8% in 2002.
Xilinx Solution
Xilinx provides significant value in an analog modem when used
to interface various ASSPs together, and provides different interface
control signals - such as USB, PCI, PCMCIA, RS-232, Ethernet and
so on. Spartan™-II FPGA devices are ideal candidates for this low-cost
application. Please view the presentation
to see how Xilinx solutions can help you build products in this
fast evolving market place.
