V.34/Group 3 H i gh Performance Fax Modem Family

The Conexant™ FM336 High Performance Fax Modem family offers ITU-T

V.34 half-duplex mode operation that supports synchronous Group 3 facsimile

send and receive speeds up to 33600 bits per second (bps). The FM336-D and

FM336-D90 support ITU-T V.34 duplex data and synchronous/asynchronous

modes with rates up to 33600 bps. The FM336-D90 also supports ITU-T V.90

PCM mode, which can receive data at speeds up to 56 Kbps.

The device has low voltage operation and is housed in a 100-pin Plastic Quad

Flat Package (PQFP). The modem’s small size and low power consumption

allow the design of compact system enclosures for use in industrial, office, and

home environments. Table 1 lists the FM336 Modem Family models and

features.

This data sheet is for the FM336 family of modems, which includes all of the

features of the FM336 version, the duplex data mode option, and the V.90 PCM

mode option. For more information on these features, refer to the FM336 High

Performance Fax Modem Designer's Guide, the FM336-D V.34/Group 3 High

Performance Fax Modem with Duplex Data Modes Supplement, and the

FM336-D90 V.34/Group 3 High Performance Fax Modem with V.90 PCM Mode

Supplement.

Utilizing V.34 and V.90 techniques to optimize modem configuration for line

conditions, the modem connects at the optimal selected data rate that the

channel can support from 2400 bps up to 56000 bps. The modem can operate

over the Public Switched Telephone Network (PSTN) through a line terminator

provided by a Data Access Arrangement (DAA).

V.34/Group 3 High Performance Fax Modem Family FM336

100086B Conexant 3

Group3 Facsimi l e M odem

(Entire FM 336 Fami ly)

The modem satisfies the requirements specified in

ITU-T recommendations V.34 half-duplex, V.17, V.29,

V.27 ter, V.21, and meets the binary signaling

requirements of V.8 and T.30 with Annex F.

Internal HDLC support eliminates the need for an

external serial input/output (SIO) device in the DTE for

products incorporating error detection and T.30

protocol. The modem can perform HDLC framing per

T.30 at all data speeds. CRC generation/checking

along with zero insertion/deletion enhances

SDLC/HDLC frame operations. An FSK flag pattern

detector facilitates FSK detection during high-speed

reception. The modem features a programmable

DTMF transmitter/receiver and three programmable

tone detectors.

Duplex Data Mode (-D / -D90)

The duplex data mode supports Internet facsimile

applications. The modem can connect at the highest

data rate up to 33600 bps with auto fall back to

V.32 bis. The FM336-D and FM336-D90 modem

satisfies the requirements specified in ITU-T

recommendations V.34, V.32 bis, V.32, V.22 bis, V.22,

V.23, V.21, Bell 212A, and Bell 103.

ITU-T V.90 PCM Mode (-D90)

The ITU-T V.90 PCM mode can receive data at speeds

up to 56 Kbps from a digitally connected V.90 central

site modem. The FM336-D90 takes advantage of the

PSTN which is primary to the central office local loop

and is ideal for applications such as remote access to

an Internet Service Provider (ISP), online service, or

corporate intranet. The modem can send upstream

data at speeds up to V.34 rate.

Technical Specif ications

The single device modem provides the processing

core for a complete facsimile modem design.

Configurations and Rates

The selectable modem configurations, signaling rates,

and data rates are listed in Table 2.

Automatic Mode Selection (-D / -D90)

When Automatic Mode Selection (AMS) is enabled, the

modem configures itself to the highest compatible data

rate supported by the remote modem. Automode

operation is supported in V.90 (-D90 only), V.34,

V.32 bis, V.32, V.22 bis, V.22, V.21, V.23, Bell 212A,

and Bell 103 modes.

Automatic Rate Adaptation

In V.34 duplex, V.34 half-duplex, and V.32 bis modes,

Automatic Rate Adaptation (ARA) can be enabled to

select the optimal highest acceptable data rate based

on the Eye Quality Monitor (EQM). This selection

occurs during startup.

Two ARA modes are available. ARA in ROM is an

adaptive selection made by the modem based upon a

fixed ROM table. ARA in RAM is based on the host

programmable RAM table and can be changed by the

user.

Data Encodi ng (-D / -D90)

The data encoding conforms to ITU-T

recommendations V.90 (-D90 only), V.34, V.32 bis,

V.32, V.17, V.29, V.27 ter, V.22 bis, V.22, V.23, or

V.21, and is compatible with Bell 208, 212A, or 103,

depending on the configuration.

Tone Generation and Supervisory Tone Detection

The modem can generate single or dual voice-band

tones from 0 Hz to 3600 Hz with a resolution of

0.15 Hz and an accuracy of ± 0.01%. Tones over

3000 Hz are attenuated. DTMF tone generation allows

the modem to operate as a programmable DTMF

dialer.

Three parallel tone detectors (A, B, and C) are

provided for supervisory tone detection. The signal

path to these detectors is separate from the main

received signal path.

Each tone detector consists of two cascaded second

order IIR biquad filters. The coefficients are host

programmable. Each fourth order filter is followed by a

level detector which has host programmable turn-on

and turn-off thresholds allowing hysteresis. A pre-filter

and squarer precede tone detector C. This circuit is

useful for detecting a tone with a frequency equal to

the difference between two tones that may be

simultaneously present on the line. The squarer may

be disabled by the SQDIS bit causing tone detector C

to be an eight-order filter. The tone detectors are

disabled in data mode.

The tone detection sample rate is 9600 Hz in V.8 and

V.34 modes and is 7200 Hz in non-V.34 modes. The

default call progress filter coefficients are based on a

7200 Hz sampling rate and apply to non-V.34 modes

only. The maximum detection bandwidth is equal to

one-half the sample rate.

Auto-Dialing and Auto-Answering Control

Features are provided to allow the host to perform

auto-dialing and auto-answering. These functions

include DTMF or pulse dialing, ring detection, and a

comprehensive supervisory tone detection scheme.

The major control parameters are host programmable.

Transmitted Data Spectrum

The transmitter spectrum is shaped by raised cosine

filter functions, either the square root of 12.5% (V.34,

V.32 bis, V.32), 20% (V.17 and V.29), 50% (V.27 ter,

Bell 208), or 75% (V.22 bis, Bell 212A).

Transmit Level

The transmitter output level is selectable from 0 dBm

to –15 dBm in 1-dB steps and is accurate to ±0.5 dB

when used with an external hybrid. The output level

can also be tuned by changing a gain constant in the

modem DSP RAM. The maximum V.34 transmit level

for acceptable receive performance should not exceed

–9 dBm.

Answer Tone (-D / -D90)

When the NV25 bit is a zero, the modem generates a

2100 Hz answer tone at the beginning of the answer

handshake for 5.0 seconds (V.8) or 3.6 seconds (V.32

bis, V.32, V.22 bis, V.22, V.23, and V.21). The answer

tone has 180° phase reversals every 0.45 seconds to

disable network echo cancellers (V.8, V.32 bis, V.32).

Receive Level

The modem satisfies performance requirements for

received line signal levels from 0 dBm to –43 dBm

measured at the receiver analog (TIP and RING) input

in V.17, V.29, V.27 ter, and DTMF modes. In V.90,

V.34, V.32 bis, V.32, V.22 bis, V.22, and V.23 modes,

the receive level range is from –9 dBm

(–15 dBm at RIN) to –43 dBm.

V.34/Group 3 High Performance Fax Modem Family FM336

100086B Conexant 5

Carrier Recovery

The carrier recovery circuit can track a ±7 Hz

frequency offset in the received carrier.

Echo Canceller (-D / -D90)

A data echo canceller with near-end and far-end echo

cancellation is included for 2-wire duplex

V.90/V.34/V.32 bis/V.32 operation. The combined echo

span of near and far cancellers can be up to

40 ms. The proportion allotted to each end is

automatically determined by the modem. The delay

between near-end and far-end echoes can be up to 1.2

seconds.

Async/Sync and Sync/Async Conversion

(-D / -D90)

An asynchronous-to-synchronous converter is

provided in the transmitter and a synchronous-to-

asynchronous converter is provided in the receiver.

The converters operate in both serial and parallel

modes. The asynchronous character format is 1 start

bit, 5 to 8 data bits, an optional parity bit, and 1 or 2

stop bits. Valid character size, including all bits, is 7, 8,

9, 10, or 11 bits per character. Two ranges of signaling

rates are provided:

• Basic range: +1% to –2.5%

• Extended overspeed range: +2.3% to –2.5%

When the transmit converter is operating at the basic

signaling rate, no more than one stop bit will be deleted

per 8 consecutive characters. When operating at the

extended rate, no more than one stop bit will be

deleted per 4 consecutive characters. Break handling

is performed as described in V.14.

Asynchronous characters are accepted on the TXD

serial input and are issued on the RXD serial output.

V.54 Inter-DCE Signaling (-D / -D90)

The modem supports V.54 inter-DCE signaling

procedures in synchronous and asynchronous

configurations. Transmission and detection of the

preparatory, acknowledgment, and termination phases

as defined in V.54 are provided. Three control bits

(V54T, V54A, and V54P) in the transmitter allow the

host to send the appropriate bit patterns. Three control

bits (V54TE, V54AE, and V54PE) in the receiver are

used to enable one of three bit pattern detectors. A

status bit (V54DT) indicates when the selected pattern

detector has found the corresponding bit pattern.

V.13 Remote RTS Signaling (-D / -D90)

The modem supports V.13 remote RTS signaling.

Transmission and detection of signaling bit patterns in

response to a change of state in the RTS bit or the

/RTS input signal are provided. This feature may be

used to clamp/unclamp the local /RLSD and RXD

signals in response to a change in the remote /RTS

signal in order to simulate controlled carrier operation

in a constant carrier environment. The modem

automatically clamps and unclamps /RLSD.

In-Band Secondary Channel (-D / -D90)

A duplex in-band secondary channel is provided in

V.34 (all speeds) and V.32 bis/V.32 (7200 bps and

above) modes. The secondary channel operates in

parallel data mode with independent transmit and

receive interrupts and data buffers. The main channel

may operate in parallel or serial mode.

In V.34 modes, the secondary channel rate is 200 bps.

In V.32 bis/V.32 modes, the secondary channel rate is

150 bps. This rate is also host programmable in V.32

bis/V.32 modes.

FM336 V.34/Group 3 High Performance Fax Modem Family

8Conexant 100086B

Transmit and Receive FIFO Data Buffers

Two 16-byte first-in first-out (FIFO) data buffers allow

the DTE/host to output up to 16 bytes of transmit data

to the transmitter FIFO (TXFIFO) and input up to

16 bytes of accumulated received data from the

receiver FIFO (RXFIFO). The TXFIFO and RXFIFO

can be extended up to 255 bytes. The size of FIFO

extension is 255 bytes overall and can be divided

between the two FIFOs in any proportion.

The RXFIFO is always enabled. The host can enable

the TXFIFO. Status bits indicate when the TXFIFO is

not full, the TXFIFO is half-full (eight or more bytes

loaded), the RXFIFO is empty, and the RXFIFO is half-

full. An interrupt mask register allows an interrupt

request to be generated whenever the status bits

change state.

DMA Support for Interrupt Request Lines

DMA support is available in synchronous data modes.

When DMA support is enabled, the modem /RI and

/DSR lines are assigned to Transmitter Request

(TXRQ) and Receiver Request (RXRQ) hardware

output interrupt request lines, respectively. The TXRQ

and RXRQ signals follow the assertion of the Transmit

Data Buffer Empty (TDBE) and Receive Data Buffer

Full (RDBF) interrupt bits, thereby allowing the

DTE/host to respond immediately to the interrupt

request without masking out status bits to determine

the interrupt source.

Caller ID Demodulation

Caller ID information can be demodulated in V.23 1200

receive configuration and presented to the DTE/host in

serial (RXD) or parallel (RBUFFER) form.

Telephone Line Inter face

Line Transformer Interface. V.34 places high

requirements upon the Data Access Arrangement

(DAA) correction to the telephone line. Due to the

wider bandwidth requirement at a symbol rate of

3429 symbols/second, the DAA must maintain linearity

from 150 Hz to 3950 Hz.

Relay Control. Direct control of the off-hook and

talk/data relays is provided. Internal relay drivers allow

direct connection to the off-hook and talk/data relays.

The talk/data relay output can optionally be used for

pulse dial.

Speaker Interface. A SPKR output is provided with

on/off and volume control logic incorporated in the

modem, requiring only an external amplifier to drive a

speaker.

Hardware Interface Signals

Functional interface signals are shown in Figure 1. In

this diagram, an active low signal is indicated by a

forward slash “/” (/RESET). A clock intended to

activate logic on its rising edge (low-to-high transition)

is called active high (TDCLK), while a clock intended to

activate logic on its falling edge (high-to-low transition)

is called active low (/RDCLK).

Modem pin assignments are shown in Figure 2. Signal

descriptions are listed in Table 3.

Power and Maximum Ratings

Current and power requirements are listed in Table 4.

Absolute maximum ratings are listed in Table 5.

Clock Sources

The modem is offered in two configurations depending

upon the selected clock source. One configuration

utilizes a crystal source and the other uses an

oscillator source.

For the crystal configuration, the crystal is connected

to XTLI (pin 85) and XTLO (pin 86). For the oscillator

source, the oscillator is connected to CLKIN (pin 85)

and XTLO (pin 86) is not connected.

Package Dimensions

The package dimensions are shown in Figure 3.
