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 Conexant SmartACFL 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, onboard 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.

V.90/K56flex Modem Device Sets with SmartDAA Technology for Low Power Applications
Data/Fax Modes
In V.90/K56flex data modem mode, the modem can
receive data from a digitally connected central site
modem (CSM) at line speeds up to 56 kbps.
Asymmetrical data transmission supports sending
data up to V.34 rates; this mode can fallback to fullduplex V.34 mode, and to lower rates as dictated by
line conditions.
In V.34 data mode, the modem operates at line
speeds up to 33.6 kbps. Error correction (V.42/MNP
2-4) and data compression (V.42 bis/MNP 5)
maximize data transfer integrity and boost average
data throughput up to 230.4 kbps. Non-errorcorrecting mode is also supported.
Data modem modes perform complete handshake
and data rate negotiations. Using V.34 modulation to
optimize modem configuration for line conditions, the
modem can connect at the highest data rate that the
channel can support from 33600 bps down to 2400
bps with automatic fallback. Automode operation in
V.34 is provided in accordance with PN3320 and in
V.32 bis in accordance with PN2330. All tone and
pattern detection functions required by the applicable
ITU or Bell standard are supported.
In V.32 bis mode, the modem operates at line
speeds up to 14.4 kbps.
In V.22 bis fast connect mode, the modem can
connect at 2400 bps with a very short training time,
which is very efficient for small data transfers.
In fax modem mode, the modem can operate in 2wire, half-duplex, synchronous mode and can
support Group 3 facsimile send and receive speeds
of 14400, 12000, 9600, 7200, 4800, and 2400 bps.
Fax data transmission and reception performed by
the modem are controlled and monitored through the
EIA/TIA-578 Fax Class 1, T.30 Fax Class 1.0, or Fax
Class 2 command interface. Full HDLC formatting,
zero insertion/deletion, and CRC
generation/checking are provided. Both transmit and
receive fax data are buffered within the modem. Data
transfer to and from DTE is flow controlled by
XON/XOFF and RTS/CTS.

SmartACFL
Synchronous Access Mode (SAM) - Video
Conferencing
V.80 Synchronous Access Mode between the
modem and the host/DTE is provided for hostcontrolled communication protocols, e.g., H.324
video conferencing applications.
Voice-call-first (VCF) before switching to a
videophone call is also supported.
Worldwide Operation
The modem operates in US/Japan/Canada/TBR21
and other countries. Country dependent parameters
for functions such as dialing, carrier transmit level,
calling tone, call progress tone detection, answer
tone detection, blacklisting, and relay control are
programmable by ConfigurACE II for Windows.
SmartDAA technology allows a single PCB design
and single BOM to be homologated worldwide.
Advanced features such as digital PBX protection
are also supported.
TAM Mode
TAM Mode features include 8-bit µ-Law, A-Law, and
linear coding at 8 kHz sample rate. Full-duplex voice
supports concurrent voice receive and transmit.
Tone detection and generation, call discrimination,
and concurrent DTMF detection are also supported.
ADPCM (4-bit IMA) coding is supported to meet
Microsoft WHQL logo requirements.
TAM Mode is supported by three submodes:
1. Online Voice Command Mode supports
connection to the telephone line or, for the S
model, a handset.
2. Voice Receive Mode supports recording voice or
audio data input from the telephone line or, for
the S model, a microphone/handset.
3. Voice Transmit Mode supports playback of voice
or audio data to the telephone line or, for the S
model, a speaker/handset.

V.90/K56flex Modem Device Sets with SmartDAA Technology for Low Power Applications
The voice interface can be in the form of a headset,
handset or a microphone and speaker (half-duplex
speakerphone). Handset echo cancellation supports
handset use through a hybrid.
Voice/Speakerphone Mode (S Models)
S models include additional telephone handset,
external microphone, and external speaker
interfaces that support voice and full-duplex
speakerphone operation.
Hands-free full-duplex telephone operation is
supported in Speakerphone Mode under host
control. Speakerphone Mode features an advanced
proprietary speakerphone algorithm which supports
full-duplex voice conversation with acoustic, line, and
handset echo cancellation. Parameters are
constantly adjusted to maintain stability with
automatic fallback from full-duplex to pseudo-duplex
operation. The speakerphone algorithm allows
position independent placement of microphone and
speaker. The host can separately control volume,
muting, and AGC in microphone and speaker
channels.
V.70 DSVD Mode using RCDSVD SCP Device
(S Models)
GSM (Parallel Host or PC Card Interface)
GSM operation requires installation of 4M (512k x 8)
ROM (56 models) or 2M ROM (33 and 14 models).
ON-board DSVD is not available when the 4 Mbit
ROM is installed since the MCU port PB5 is used for
address line 18 rather than RCDSVD SCP chip
select output (~SVOSEL).
Features supported in GSM operation include:
On-board DSVD operation requires installation of the
optional RCDSVD SCP (R6715-14). GSM operation
is not available when the RCDSVD SCP is
connected because MCU port PB5 is used for SCP
chip select output (~SVDSEL) rather than address
line A18 output which is needed to support the 4M
ROM.
DSVD provides full-duplex digital simultaneous voice
and data over a single telephone line. DSVD uses
codecs in the RCDSVD SCP to code (compress)
analog speech signals on the RCDSVD LINEIN pin
or MICIN pin for passing to the modem controller in
digitized form. DSVD also decodes (decompresses)
coded speech received from the modem controller
for routing to the RCDSVD LINEOUT pin or
SPKP/SPKN pins in analog form.
• Data modem

interoperable G.729 and G.729 Annex A with
interoperable G.729 Annex B. Voice activity
detection supports speech coding at an average bit
rate significantly lower than 8.0 kbps.
DSVD decoder timing recovery algorithm
compensates for clock skew, asynchronous host-todecoder data transfer delay, intervening variable
length data block transmission delay, and loss of
encoded speech data.

In Handset Mode, the RCDSVD SCP interfaces to
the telephone interface circuit using the Line Input
(LINEIN) and Line Out (LINEOUT) lines. In Headset
or Speakerphone Mode, the RCDSVD SCP
interfaces to the audio interface circuit using the
Microphone Input (MICIN) and Speaker out (SPKR)
lines.

Modem Data Pump (MDP)
RCDSVD Speech Codec Processor (SCP)
(Optional)
The Modem Data Pump (MDP) supports data/fax
modem, voice record from and playback to the
telephone line, and optional voice/full-duplex
speakerphone operation. The MDP communicates
with the MCU via parallel bus, serial data and clock,
and serial voice (optional) signals. Downloadable
architecture allows upgrading of MDP code from the
MCU.
The RCDSVD SCP (R6715-14), required for onboard DSVD operation, is packaged in a 100-pin
PQFP. The 56.448 MHz crystal frequency is
supplied by the MDP XCLK output.
MCU/MCUP Firmware
MCU/MCUP firmware performs processing of
general modem control, command sets, data
modem, error correction and data compression
(ECC), fax class 1, fax class 2, DSVD,
voice/audio/TAM/speakerphone, W-class, V.80,
analog cellular, GSM, and serial DTE/parallel
host/PC Card interface functions according to
modem models (Table 1).
The MDP, packaged in a 100-pin TQFP, includes a
modem controller interface, a digital signal processor
(DSP), a voice codec (VC) interface, and a
SmartDAA Interface.
The MDP performs telephone line signal
modulation/demodulation in a hardware DSP which
reduces computational load on the host processor.
Downloadable architecture allows updating of MDP
executable code.
Configurations of the modem firmware are provided
to support parallel host bus interface (MCU), serial
DTE interface (MCU) or PC Card interface (MCUP)
operation.
The modem firmware is provided in object code form
for the OEM to program into external ROM/flash
ROM. The modem firmware may also be provided in
source code form under a source code addendum
license agreement.
The SmartDAA Interface communicates with, and
supplies power and clock to, the LSD through the
DIB.
The input clock frequency is 28.224 MHz and is
supplied by the MCU. The operating voltage is +3.3V
with +5V tolerant inputs.
ADPCM voice processing is supported.
Downloading of MDP code from the MCU is
supported.
Digital Isolation Barrier (DIB) (OEM Supplied)
The DIB electrically DC isolates the MDP from the
LSD. The MDP is connected to a fixed digital ground
and operates with standard CMOS logic levels. The
LSD is connected to a floating ground and can
tolerate high voltage input (compatible with
telephone line and typical surge requirements).
A digital transformer (DXFMR) in the DIB power
channel couples power and clock digital waveforms
from the MDP to the LSD.
The DIB data channel supports bidirectional halfduplex serial transfer of data, control, and status
information between the MDP and the LSD over two
lines.

SmartDAA Line Side Device (LSD)
The LSD includes a Line Side DIB Interface (LSDI),
a coder/decoder (codec), and a Telephone Line
Interface (TLI).
The LSDI communicates with, and receives power
and clock from, the SmartDAA interface in the MDP
through the DIB.
LSD power is received from the top of the DIB
DXFMR secondary winding through a half-wave
rectifying diode and capacitive power filter circuit.
The CLK input is also accepted from the top of the
DXFMR secondary winding through a capacitor and
a resistor in series.
Information is transferred between the LSD and the
MDP through the DIB_P and DIB_N pins. These pins
connect to the MDP DIB_DATAP and DIB_DATAN
pins, respectively, through the DIB.
The TLI integrates DAA and direct telephone line
interface functions and connects directly to the line
TIP and RING pins, as well as to external line
protection components.
Direct LSD connection to TIP and RING allows realtime measurement of telephone line parameters,
such as the telephone central office (CO) battery
voltage and individual telephone line (copper wire)
resistance. Direct LSD connection also allows
dynamic regulation of the off-hook TIP and RING
voltage and total current drawn from the CO. This
allows the modem to maintain compliance with U.S.
and worldwide regulations and to actively control the
DAA power dissipation.
Voice Codec (VC)
The optional VC, packaged 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.
