CONEXANT RC144LD

5&/'5&/'DQG5&/'
Integrated V.90/K56flex/V.34/V.32bis Modem Device Sets
for Low Power Applications
The Conexant RC56LD, RC336LD, and RC144LD
Modem Device Set supports data/fax, V.80 synchronous
access mode, world-class, voice/TAM/ telephony
extensions, speakerphone, AudioSpan, DSVD, and
cellular/GSM operation depending upon the model, ROM
size, and installed firmware (Table 1). The modem
supports the following primary data modulations: ITU-T
V.90/K56flex (RC56), V.34 (RC56 and RC336) and
V.32bis.
The modem is designed to operate with dial-up telephone
lines in the U.S. and world-wide. PC Card interface
models also support analog cellular direct connect and
GSM direct connect. Parallel host interface models can
support either analog cellular direct connect and GSM
direct connect or telephony extensions. Serial DTE
interface models support telephony extensions.
Low profile, small PQFP/TQFP packages and low voltage
operation with low power consumption make this device
set ideal for laptop, notebook, and palmtop applications
using parallel host or serial DTE interface with the MCU or
using PC Card interface with the MCUP.
The device set consists of an 8-bit microcomputer (MCU)
or MCU with built-in PC Card interface (MCUP) in a 128pin TQFP and a modem data pump (MDP) in a 144-pin
TQFP or 100-pin PQFP. The SP model can also be
ordered with an RCDSVD Speech Codec Processor
(SCP) in a 100-pin PQFP to support DSVD.
The MCUP PC Card interface supports two peripheral
channels, one channel for the modem and a second
channel for an optional user-defined function (Function 2).
Downloadable architecture supports downloading of
modem firmware from the host/DTE to the MCU and,
transparently to the host/DTE, the downloading of MDP
code modules from the MCU.
The modem operates by executing firmware from external
1Mbit (128k x 8) RAM and 2Mbit (256k x 8) ROM/flash
ROM. The RC336 and RC144 can alternatively use
external 1Mbit or 2Mbit ROM/flash ROM and either
internal or external 32k x 8 RAM. Double the normal ROM
size for GSM operation.
In V.90/K56flex mode (RC56), the modem can receive
data at speeds up to 56 kbps from a digitally connected
V.90- or K56flex-compatible central site modem. Taking
advantage of the PSTN which is primarily digital except
for the client modem to central office local loop,
V.90/K56flex modems are ideal for applications such as
remote access to an Internet Service Provider (ISP), online service, or corporate site. The modem can send data
at speeds up to V.34 rates.
'DWD 6KHHW
In V.34 data mode (RC56 and RC336), 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-error-correcting mode is
also supported.
In V.32 bis mode, the modem operates at line speeds up
to 14.4 kbps.
The modem supports fax Group 3 send and receive rates
up to 33.6 kbps and supports T.30 protocol.
V.80 synchronous access mode supports host-based
communication protocols, e. g., H.324 video conferencing.
In voice/TAM mode, enhanced 2-bit or 4-bit per sample
ADPCM coding and decoding at 7200 Hz sample rate
allows efficient digital storage of voice/audio. This mode
supports applications such as digital telephone answering
machine (TAM), voice annotation, and recording from and
playback to the telephone line.
SP models support position independent, full-duplex
speakerphone (FDSP) operation using microphone and
speaker, as well as other voice/TAM applications using
handset or headset. SP models also support AudioSpan
(analog simultaneous audio/voice and data) operation
with a data rate of 4.8 kbps with audio.
SP models, using the optional RCDSVD SCP device,
support hardware-based (on-board) V.70 DSVD (digital
simultaneous voice and data) with speech coding per
ITU-T interoperable G.729 and G.729 Annex A with
interoperable G.729 Annex B. GSM operation with 4M
ROM is not available when the RCDSVD SCP is used.
Host-based DSVD is supported in all models, however,
the host PC must supply full-duplex sound support,
typically to a microphone/speaker, such as provided by
Conexant WaveArtist devices or a sound card.
GSM operation supports data services offered by the
Global System for Mobile Communications network: data
transmissions to PSTN, ISDN or GSM users. GSM data
operation allows data and fax transfer, and connection to
videotex.
Analog cellular and GSM direct connect operation is
supported by licensed firmware for specific phone types.
A common PC board design can support data/fax, V.80,
voice/TAM/telephone extensions, speakerphone,
AudioSpan, and host- or on-board DSVD operation
depending on the installed modem devices.
Accelerator kits and reference designs are available to
minimize application design time and costs. PC-based
“ConfigurACE™ II for Windows” software allows MCU
firmware to be customized.

Description
General
The modem device set, consisting of separate
microcontroller (MCU/MCUP), modem data pump (MDP),
and optional RCDSVD Speech Codec Processor (SCP)
devices, provides the processing core for a complete
modem design.
For data/fax/V.80/voice/TAM/speakerphone/hostDSVD/AudioSpan operation, only the microcontroller
(MCU) and modem data pump (MDP) devices are
needed. The OEM adds an MCU crystal, discrete
components, and a telephone line/telephone/voice/TAM/analog cellular/GSM cellular interface circuit to
complete the modem system. Telephony extensions are
supported in the serial DTE models and optionally in the
parallel host models. Optional on-board DSVD operation
is supported with addition of the RCDSVD Speech Codec
Processor (SCP) device to an SP model. Table 1 shows
the supported functions by product family.
Dialing, call progress, V.80, telephone line interface,
voice/TAM, speakerphone, AudioSpan, DSVD, analog
cellular phone, and GSM phone interface functions are
supported and controlled through the AT command set.
Connection to the host/DTE is supported by serial DTE
interface (Figure 1), parallel host interface (Figure 2), or
PC Card interface (Figure 3), depending on modem model
and installed firmware. GSM operation is supported for
parallel host and PC Card interface only.
For U.S. operation, the modem can operate with a 1-relay
data/fax/TAM DAA interface (Figure 4) or a 2-relay
data/fax/TAM/V.61/Speakerphone DAA interface (Figure
5).
Data/Fax Modes
In V.90/K56flex data modem mode (RC56), the modem
can receive data from a digital source using a V.90- or
K56flex-compatible central site modem at line speeds up
to 56 kbps. Asymmetrical data transmission supports
sending data at speeds up to V.34 rates. This mode can
fallback to full-duplex V.34 mode.
In V.34 data modem mode (RC56 and RC336), the
modem can operate in 2-wire, full-duplex, asynchronous
modes at line rates up to 33.6 kbps. 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 33.6 kbps to
300 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 fax modem mode, the modem can operate in 2-wire,
half-duplex, synchronous mode and can support Group 3
facsimile send and receive speeds of 33600, 31200,
28800, 26400, 24000, 21600, 19200, 16800, 14400,
12000, 9600, 7200, 4800, and 2400 bps. 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 at speeds up to 33.6
kbps with automatic rate adaption. Fax data transmission
and reception performed by the modem are controlled and
monitored through the EIA/TIA-578 Fax Class 1, T.31 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 the DTE is flow
controlled by XON/XOFF and RTS/CTS.
Synchronous Access Mode (SAM)
V.80 synchronous access mode between the modem and
the host/DTE is provided for host-based communication
protocols, e.g., H.324 video conferencing applications.
Voice-call-first (VCF) before switching to a videophone
call is also supported.
Voice/TAM Mode is supported by three submodes:
1.
Online Voice Command Mode supports connection to
the telephone line or, for SP models, a handset.
2.
Voice Receive Mode supports recording voice or
audio data input at the RIN pin, typically from the
telephone line or, for SP models, a
microphone/handset.
Voice Transmit Mode supports playback of voice or
audio data to the TXA1/TXA2 output, typically to the
telephone line or, for SP models, a speaker/handset.
Telephony Extension Operation
Extension pickup/remote hangup detection and line-in-use
detection are supported in serial DTE models optionally
(in lieu of cellular/GSM support) in parallel host models.
MD213
The speakerphone mode provides hands-free full-duplex
telephone operation under host control. The host can
separately control volume, muting, and AGC in
microphone and speaker channels.
AudioSpan Mode (SP Models)
AudioSpan provides full-duplex analog simultaneous
audio/voice and data over a telephone line at a data rate
of 4800 bps with audio using V.61 modulation. AudioSpan
can send any type of audio waveform, including music.
Data can be sent with or without error correction. The
audio/voice interface can be in the form of a headset,
handset, or a microphone and speaker. Handset echo
cancellation is provided.
DSVD Mode using RCDSVD SCP Device (SP Models)
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 operates in accordance with ITU-T interoperable
G.729 and G.729 Annex A with interoperable G.729
Annex B. Voice activity detection supports speech coding
at average bit rate significantly lower than 8.0 kbps.
Voice/TAM Mode
Voice/TAM Mode features include enhanced ADPCM
compression/decompression, tone detection/generation
and call discrimination, concurrent DTMF detection, and
8-bit monophonic audio data encoding.
Speakerphone Mode (SP Models)
The speakerphone mode features an advanced
proprietary speakerphone algorithm which supports fullduplex voice conversation with both acoustic and line
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.
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
signal on the RCDSVD LINEIN pin or MICIN pin for
passing to the modem controller in digitized form, and to
decode (decompress) coded speech received from the
modem controller for routing to the RCDSVD LINEOUT
pin or SPKP/SPKN pins in analog form.
World Class Operation
W-class functions support modem operation in multiple
countries. Additional modem functions are provided in
areas such as dialing, carrier transmit level, calling tone,
call progress tone detection, answer tone detection,
blacklisting, and relay control. Country dependent
parameters are programmable by ConfigurACE II for
Windows.

5&/'5&/'DQG5&/'
DSVD decoder timing recovery algorithm compensates for
clock skew, asynchronous host-to-decoder data transfer
delay, intervening variable length data block transmission
delay, and loss of encoded speech data.
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.
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.
Host-Based DSVD
All modem models support host-based ITU-T V.70 DSVD.
The RCDSVD SCP (R6715) is not required. V.70 software
drivers for Windows 95 are provided which support a
speech/audio bit rate of significantly less than 8.0 kbps by
implementing interoperable G.729 and G.729 Annex A
with interoperable G.729 Annex B. The minimum PC
performance recommended for host-based DSVD is
Conexant

5&/'5&/'DQG5&/'
,QWHJUDWHG9.IOH[99ELV0RGHP'HYLFH6HWV
150 MHz Pentium or equivalent. The V.70 software
drivers require about 10% of the MIPS available in a
Pentium 150 MHz class PC. The host PC must supply fullduplex sound support, typically to a microphone/speaker,
such as provided by Conexant WaveArtist devices or a
sound card. The modem is configured for host-based V.70
via AT commands, and, when using a TAPI-compliant
communication application, the V.70 software drivers will
automatically run upon a successful V.70 connection.
Sleep Mode
Sleep Mode is supported in the modem device set and the
RCDSVD SCP device.
GSM (Parallel Host or PC Card Interface)
GSM operation requires installation of 4M (RC56) or 2M
(RC336 or RC144) ROM. On-board DSVD is not available
when the 4M ROM is installed because MCU port PB5 is
used for address line A18 output rather than RCDSVD
SCP chip select output (~SVDSEL).
Features supported in GSM operation include:
• Data modem
− V.21, V.23, V.22, V.22 bis, V.32
− ISDN interoperability: 300 bps to 9600 bps
• Transparent asynchronous mode up to 9600 bps
• Non-transparent mode (RLP) up to 9600 bps
• Fax modem send and receive rate up to 9600 bps
• AT GSM commands (ETSI 07.07)
• GSM direct connect
• Firmware interface for OEM-provided phone driver
• Automatic GSM cable presence detection
• Built-in parallel host (16550A UART) interface
ADPCM voice processing is supported.
Downloading of MDP code from the MCU is supported.
Microcontroller (MCU/MCUP)
The MCU/MCUP is a Conexant 8-bit microcomputer with
pins to support serial DTE/parallel host bus/PC Card,
MDP, voice/TAM, speakerphone, and RCDSVD SCP
interface operation, depending upon model and installed
firmware. The operating voltage is +3.3V with +5V tolerant
inputs.
The MCU connects to the DTE/host via a V.24 (EIA/TIA232-E) serial DTE interface or a parallel host bus
depending on installed MCU firmware, whereas the
MCUP connects to a PC Card socket via built-in PC Card
interface. Unless otherwise stated, references to general
MCU functions also include the MCUP.
The MCU performs the command processing and host
interface functions. The crystal frequency is 28.224 MHz.
The MCU outputs a 28.224 MHz clock to the MDP
eliminating need for a separate MDP crystal circuit.
The MCU connects to the MDP via dedicated lines and
the external bus. The external bus also connects to OEMsupplied RAM (if more than 32 kbytes are required), OEMsupplied ROM/flash ROM, and to the optional RCDSVD
SCP. The MCU/MCUP provides 32 kbytes of internal RAM
that can be used instead of external RAM for 32-kbyte
RAM applications.
Modem Data Pump (MDP)
The data/fax/voice/speakerphone modem data pump
(MDP) is a Conexant R6785 packaged in a 144-pin TQFP
or a R6764 packaged in a 100-pin PQFP. The input clock
frequency is 28.224 MHz and is supplied by the MCU. An
internal phase locked loop (PLL) circuit supports 56.448
MHz internal operation. The operating voltage is +3.3V
supplied by the MCU with +5V tolerant inputs. The R6785
supports either +3.3V (~SET3V is tied to AGND) or +5V
(~SET3V pin is NC) analog signal interface; the R6764
supports +3.3V analog signal interface.
In V.90/K56flex data modem mode (RC56), the MDP can
receive data from a digital source using a V.90- or
K56flex-compatible central site modem at line speeds up
to 56 kbps. Asymmetrical data transmission supports
sending data at speeds up to V.34 rates.
In V.34 data modem mode (RC56 and RC335), the MDP
can operate in 2-wire, full-duplex,
synchronous/asynchronous modes at line rates up to 33.6
kbps. Using V.34 modulation to optimize modem
configuration for line conditions, the MDP can connect at
the highest data rate that the channel can support from
33.6 kbps to 300 bps with automatic fallback. Automode
operation in V.34 is provided in accordance with PN3320
and in V.32 bis in accordance with PN2330.
In V.32 bis mode, the MDP can operate at line speeds up
to 14.4 kbps.
8
In fax modem mode, the MDP supports Group 3 facsimile
send and receive speeds of speeds of 33600, 31200,
28800, 26400, 24000, 21600, 19200, 16800, 14400,
12000, 9600, 7200, 4800, and 2400 bps.
The MCU connects to an optional 256-byte or 2048-byte
serial EEPROM over a dedicated serial interface.
The MCU and MCUP are both packaged in a 128-pin
TQFP.
MCU Serial DTE or Parallel Host Interface
The MCU connects to the DTE/host via a V.24 (EIA/TIA232-E) serial DTE interface or a parallel host bus
depending on installed MCU firmware.
In parallel host interface, the MCU can also connect to a
PC Card connector using a Conexant PCMCIA Interface
Control Adapter (PICA) device (see data sheet Order No.
MD99) and a PCMCIA Card Information Structure (CIS)
memory device.
MCUP PC Card Interface
The MCUP incorporates a built-in PC Card interface and
CIS memory allowing the MCUP to directly connect to the
PC Card 68-pin socket without requiring external PICA
and CIS devices.
Two independent functions are supported, the modem
function and an optional user-defined Function 2. A Card
Option Configuration Register and a Configuration and
Status Register for each function allow independent
configuration/control and status reporting of the respective
function.
