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. Two FSK (V.21 Ch. 1 and V.21 Ch. 2) flag pattern detectors facilitate FSK detection during high-speed reception. The modem features a programmable DTMF transmitter/receiver and three programmable tone detectors. The FM336Plus 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 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 FM336Plus-D and FM336Plus-D90 modems satisfy 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 FM336Plus-D90 takes advantage of the PSTN which is primarily digital to the central office local loop (except for the client modem) 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 the V.34 rate. 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 Encoding The data encoding conforms to ITU-T recommendations V.90 (-D90 only), V.34, V.32 bis, V.32, V.17, V.33, 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 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. 101361A Conexant 3 FM336Plus V.34/Group 3 High Performance Fax Modem Family Supervisory Tone Detection Answer Tone (-D / -D90) 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. 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, and V.32). 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 SQDIS bit may disable the squarer causing tone detector C to be an eight-order filter. The tone detectors are disabled in data mode. 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.33, 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 dB. (RIN is 6 dB lower than TIP and RING.) 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. Carrier Recovery Auto-Dialing and Auto-Answering Control 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 nearend and far-end echoes can be up to 1.2 seconds. 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. The carrier recovery circuit can track a ±7 Hz frequency offset in the received carrier. Echo Canceller (-D / -D90) 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, V.33, 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. 4 Conexant 101361A V.34/Group 3 High Performance Fax Modem Family FM336Plus Table 2.

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. Parallel Synchronous Data 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. • Normal sync: 8-bit data for transmit and receive Data rate: 300–56000 bps (-D90) or 300–33600 bps ±0.01% SDLC/HDLC support: − Transmitter: Flag generation, 0-bit stuffing, CRC-16 or CRC-32 generation − Receiver: Flag detection, 0-bit deletion, CRC-16 or CRC-32 checking Parallel Asynchronous Data (-D / -D90) • • • In-Band Secondary Channel (-D / -D90) Data rate: 300–56000 bps (-D90) or 300–33600 bps +1%/–2.5% or +2.3%/–2.5%; 1200, 300, or 75 bps (FSK) Data bits per character: 5, 6, 7, or 8 Parity generation/checking: Odd, Even, or 9th data bit 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. Async/Sync and Sync/Async Conversion (-D / -D90) In V.34 modes, the secondary channel rate is 200 bps. 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 eight consecutive characters. When operating at the extended rate, no more than one stop bit will be deleted per four 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. 101361A 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. 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 the 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 halffull. An interrupt mask register allows an interrupt request to be generated whenever the status bits change state. Conexant 6 V.34/Group 3 High Performance Fax Modem Family FM336Plus 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. Quick Start for V.34 Half-Duplex (Conexant Proprietary) V.34 Fax Quick Startup eliminates the V.8 phase 1 segment and uses a shortened training sequence during phase 3, which can save up to 50% of the initial Phase1 to Phase 4 start up time for normal V.34 halfduplex connection. 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 Figure 1 illustrates the functional interface signals. In this diagram, an active low signal is indicated by a forward slash “/” (e.g., /RESET). A clock intended to activate logic on its rising edge (low-to-high transition) is called active high (e.g., TDCLK), while a clock intended to activate logic on its falling edge (high-tolow transition) is called active low (e.g., /RDCLK). Figure 2 illustrates the modem pin assignments. Table 3 provides the signal descriptions. ADPCM Voice Mode The Adaptive Differential Pulse Code Modulation (ADPCM) voice coder and decoder (codec) compresses and decompresses voice signals for efficient digital storage of voice messages. The codec operates at 28.8 kbps, 21.6 kbps, or 14.4 kbps (4-bit, 3-bit, or 2-bit quantization, respectively) with an 8.0 kHz sampling rate. Caller ID Demodulation Caller ID information can be demodulated in the V.23 1200 receive configuration and presented to the DTE/host in serial (RXD) or parallel (RBUFFER) form. Call Waiting Detector A tone detector is provided to perform call waiting detection and is available in V.90, V.34, V.32bis, V.32, V.17, V.29, and V.27ter modes. By default, call waiting tone levels down to approximately –28 dBm can be detected. The detector can tolerate near-end echo levels up to 10 dB above the call waiting tone level. Power and Maximum Ratings Table 4 lists the current and power requirements. Table 5 lists the absolute maximum ratings. 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 Figure 3 shows the package dimensions. Additional Information Additional design information is described in the FM336Plus V.34/Group3 High Performance Fax Modem Designer’s Guide. Telephone Line Interface Line Transformer Interface. V.90/V.34 places high requirements upon the Data Access Arrangement (DAA) connection to the telephone line.
