SmartACFLModem
V.90/K56flex/V.34/V.32bis Modem Device Sets with Microcontroller (L2702),
Modem Data Pump (P9373), SmartDAA(20463), and Optional Voice Codec (20437)
for Low Power Applications
The ConexantSmartACFL V.90/K56flex Modem Device Set with SmartDAA
technology supports analog data up to 56 Kbps, analog fax to 14.4 Kbps,
telephone answering machine (TAM), V.80 synchronous access mode, on-
board DSVD, voice/speakerphone (optional), and cellular/GSM operation.
Serial, parallel, or PC Card host interface operation is supported depending on
the selected model (Table 1).
The modem supports ITU-T V.90/K56flex, V.34 and V.32bis data
modulations and is designed to operate with dial-up telephone lines in the U.S.
and worldwide. PC Card and parallel host interface models also support analog
cellular direct connect and GSM direct connect. Low profile, small TQFP
packages and low voltage operation with low power consumption make this
device set ideal for laptop, notebook, and palmtop applications using the
parallel host or serial DTE interface with the MCU, or the PC Card interface
with the MCUP.
The SmartACFL device set consists of a Microcontroller (MCU or MCUP) in a
128-pin TQFP, a Modem Data Pump (MDP) in a 100-pin TQFP, and a Line
Side Device (LSD) (SmartDAA device) in a 32-pin TQFP. The optional Voice
Codec (VC), in a 32-pin TQFP, supports voice/full-duplex speakerphone
(FDSP) operation with interfaces to a microphone and speaker and to a
telephone handset/headset. Figure 1 identifies the major hardware signal
interfaces. The MCUP supports two peripheral channels, one channel for the
modem and a second channel for an optional user-defined function
(Function 2).
Conexant's SmartDAA technology (patent pending) eliminates the need for a
costly line transformer, relays, and opto-isolators typically used in discrete DAA
(Data Access Arrangement) implementations. The SmartDAA architecture also
simplifies product implementation by eliminating the need for country-specific
components enabling worldwide homologation of a single modem board design
and a single bill of materials (BOM).
The SmartDAA system-powered DAA operates reliably without drawing power
from the line, unlike line-powered DAAs that operate poorly when line current is
insufficient due to long lines or poor line conditions. Enhanced features, such
as monitoring of local extension status without going off-hook, are also
supported.
Incorporating Conexant’s proprietary Digital Isolation Barrier (DIB) design
(patent pending) and other innovative DAA features, the SmartDAA
architecture simplifies application design, minimizes layout area, and reduces
component cost.
