Data Sheet Order No. MD205 March 31, 1998 FM209 and FM214 9600/14400 bps MONOFAX Modem Family The Conexant™ FM209 and FM214 MONOFAX modem family offers synchronous 9600 or 14400 bits per second (bps) half-duplex modems with error detection, voice and audio codecs, full-duplex speakerphone, automatic speech recognition, DTMF reception, V.23 full-duplex, Type I Caller ID and Type II Caller ID CAS detection. It has low power consumption and is housed in a single 128-pin Thin Quad Flat Pack (TQFP) device package. The modem's small size and low power consumption allow the design of compact system enclosures for use in both office and home environments. Table 1 lists the FM209/FM214 models and features. Group 3 Facsimile Modem The modem can operate over the public switched telephone network (PSTN) through line termination provided by a data access arrangement (DAA). The modem satisfies the requirements specified in ITU-T recommendations signaling requirements of T.30. The modem operates at 14400, 12000, 9600, 7200, 4800, 2400, or 300 bps. The modem supports the V.17 signaling rates of 14400, 12000, 9600, and 7200 bps using trellis-coded modulation (TCM). In addition, the modem supports V.27 ter and V.17 short trains. The modem can also perform HDLC framing according to T.30 at 14400, 12000, 9600, 7200, 4800, 2400, or 300 bps. A FSK flag pattern (7E) detector facilitates FSK detection during V.33, V.17, V.29, and V.27 ter reception. The modem includes a programmable single/dual tone transmitter, a programmable DTMF receiver, three programmable tone detectors (which operate concurrently with the V.21 Channel 2 receiver), and a ring detector. The transmit output level is also programmable. Voice and Audio Codecs (-V Option) The voice coder/decoder (codec) compresses voice at an average rate of 2.9 kbps or at a fixed rate of 4.7 kbps with near toll quality playback at various pitch synchronized playback speeds. An average rate of 2.9 kbps provides 24 minutes of stored voice messages in 4 Mbits of memory. This voice codec allows the host controller to efficiently store and playback digital incoming messages (ICMs) and outgoing messages (OGMs). The ADPCM audio codec compresses audio signals (music/voice) at 32 kbps or 24 kbps for highest fidelity coding and reproduction. The PCM audio codec allows the host controller to transmit and receive uncompressed audio signals. Distinguishing Features

Configurations, Symbol Rates and Data Rates The selectable modem configurations, along with the corresponding symbol (baud) rates and data rates, are listed in Table 2. Scrambler/Descrambler The modem incorporates a self-synchronizing scrambler/descrambler in accordance with ITU-T V.33, V.17, V.29, and V.27 ter recommendations, depending upon the selected configuration. Data Encoding The data encoding conforms to ITU-T Channel 2, and V.23. Fixed Digital Cable Compromise Equalizer Compromise equalization can improve performance when operating over low quality lines. The modem has a selectable fixed digital compromise cable equalizer in the high speed receive and transmit data path. Transmitted Data Spectrum The transmitted data spectrum is shaped in the baseband by an excess bandwidth finite impulse response (FIR) filter with the following characteristics: When operating at 2400 baud, the transmitted spectrum is shaped by a square root of 20% raised cosine filter. When operating at 1600 baud, the transmitted spectrum is shaped by a square root of 50% raised cosine filter. When operating at 1200 baud, the transmitted spectrum is shaped by a square root of 90% raised cosine filter. The out-of-band transmitter energy levels in the 4 - 50 kHz frequency range are below -55.0 dBm. Transmit Level The transmitter output level is programmable in the DSP RAM from 0 dBm to -15.0 dBm and is accurate to ±1.0 dB. The modem adjusts the output level by digitally scaling the output to the transmitter's digital- to-analog converter. Turn-on Sequence Transmitter turn-on sequence times are shown in Table 3. Receive Dynamic Range The receiver satisfies PSTN performance requirements for received line signal levels from 0 dBm to -43 dBm measured at the Receiver Analog Input (RXA) input. An external input buffer must be supplied between RXA and LINEIN. The default values of the programmable Received Line Signal Detector (RLSD#) turn-on and turn-off threshold levels are -43 dBm and -48 dBm, respectively. The RLSD# threshold levels can be programmed over the following range: Turn on: -10 dBm to -47 dBm Turn off: -10 dBm to -52 dBm Automatic Adaptive Equalizer An adaptive equalizer in ITU-T V.33, V.17, V.29 and V.27ter modes compensates for transmission line amplitude and group delay distortion. Receiver Timing The timing recovery circuit can track a ±0.01% frequency error in the associated transmit timing source. Carrier Recovery The carrier recovery circuit can track a ±7 Hz frequency offset in the received carrier. Turn-off Sequence Transmitter turn-off sequence times are shown in Table 4. Clamping Received Data (RXD) is clamped to a constant mark whenever RLSD# is off. V.23 Full-Duplex Features The modem can transmit and detect Break signals (continuous Space). The Mark and Space frequencies are 1300 and 2100 Hz, respectively, for 1200 bps, and 390 and 450 Hz, respectively, for 75 bps. Additional features include an optional host programmable Receive Compromise Equalizer for V.23 1200 bps reception and Caller ID mode. Default transmitter turn-on/turn-off sequence times are 10.5 ms (RTS On to CTS On) and 2.2 ms (RTS Off to CTS Off).

/G09/G0A /G0D/G0A /G09 MD205 7 Software Interface Modem functions are implemented in firmware executing in the modem DSP. The DSP RAM interface memory bits, access functions, codes, and registers are defined in the Designer’s Guide. Interface Memory The DSP communicates with the host processor by means of a dual-port, interface memory. This interface memory contains thirty-two 8-bit registers, labeled register 00h through 1Fh. Each register can be read or written by the host and the DSP. The host controls the modem operation by writing control bits to DSP interface memory and writing parameter values to DSP RAM through interface memory. The host monitors the modem operation by reading status bits from DSP interface memory and reading parameter values from DSP RAM through interface memory. An interface memory interrupt is provided. DSP RAM Access The DSP contains 16-bit word RAM. Because the DSP is optimized for performing complex arithmetic, the RAM is organized into real (X RAM) and imaginary (Y RAM) parts. The host processor can read or write both the X RAM and the Y RAM. DSP interface memory mediates data exchange between the host and DSP RAM. The address stored in interface memory RAM address registers by the host determines the DSP RAM address for data access.
