RCV56HCF PCI/CardBus Modem Designer’s Guide 1.3 TECHNICAL OVERVIEW 1.3.1 General Description The RCV56HCF Device Set provides the processing core for a complete system design featuring data/fax modem, DSVD, AudioSpan, speakerphone, voice/audio, and VoiceView depending on specific model (Table 1-1). Note: RCV56HCF Device Set refers to the family of single device modem models listed in Table 1-1. The modem is the full-featured, self-contained data modem/fax modem/DSVD/voice/audio/speakerphone solution.
RCV56HCF PCI/CardBus Modem Designer’s Guide Speakerphone Mode (ISDN and SP Models) The speakerphone mode features an advanced proprietary speakerphone algorithm which supports full-duplex 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.
RCV56HCF PCI/CardBus Modem Designer’s Guide 1.3.5.2 Serial EEPROM Interface A serial EEPROM is required to store the Maximum Latency, Minimum Grant, Device ID, Vendor ID, Subsystem ID, and Subsystem Vendor ID parameters for the PCI Configuration Space Header. The serial EEPROM interface connects to an Microchip 93LC66B, Atmel AT93C66, or equivalent 256 x 16 serial EEPROM.

Pulse dialing is supported in accordance with EIA/TIA-496-A. Blind Dialing. The modem can blind dial in the absence of a dial tone if enabled by the X0, X1, or X3 command.
RCV56HCF PCI/CardBus Modem Designer’s Guide Fall Forward/Fallback (K56flex, V.34/V.32 bis/V.32) During initial handshake, the modem will fallback to the optimal line connection within K56flex/V.34/V.32 bis/V.32 mode depending upon signal quality if automode is enabled by the +MS command. When connected in K56flex/V.34/V.32 bis/V.
RCV56HCF PCI/CardBus Modem Designer’s Guide 2.6.1 Online Voice Command Mode This mode results from the connection to the telephone line or a voice/audio I/O device (e.g., microphone, speaker, or handset) through the use of the +FCLASS=8 and +VLS commands. After mode entry, AT commands can be entered without aborting the connection. 2.6.
RCV56HCF PCI/CardBus Modem Designer’s Guide software control modem operation. Most VoiceView commands use an extended syntax starting with the characters "-S", which signifies the capability to switch between voice and data. 2.11 CALLER ID Caller ID can be enabled/disabled using the +VCID command. When enabled, caller ID information (date, time, caller code, and name) can be passed to the DTE in formatted or unformatted form.

RCV56HCF PCI/CardBus Modem Designer’s Guide 4. DESIGN CONSIDERATIONS Good engineering practices must be followed when designing a printed circuit board (PCB) containing the modem device. This is especially important considering the high data bit rate, high fax rate, record/play of analog speech and music audio, and full-duplex speakerphone operation. Suppression of noise is essential to the proper operation and performance of the modem and interfacing audio and DAA circuits.
RCV56HCF PCI/CardBus Modem Designer’s Guide 3. 4. 5. 6. 7. Once sections have been roughly defined, place the components starting with the connectors and jacks. a) Allow sufficient clearance around connectors and jacks for mating connectors and plugs. b) Allow sufficient clearance around components for power and ground traces. c) Allow sufficient clearance around sockets to allow the use of component extractors. First, place the mixed analog/digital components (e.g.
RCV56HCF PCI/CardBus Modem Designer’s Guide 10. Minimize the number of through-hole connections (feedthroughs/vias) on traces carrying high frequency signals. 11. Keep all signal traces away from crystal circuits. 12. Distribute high frequency signals continuously on a single trace rather than several traces radiating from one point. 13. Provide adequate clearance (e.g., 60 mil minimum) around feedthroughs in any internal planes in the DAA circuit. 14.
RCV56HCF PCI/CardBus Modem Designer’s Guide 4.1.5 Ground Planes 1. In a 2-layer design, provide digital and analog ground plane areas in all unused space around and under digital and analog circuit components (exclusive of the DAA), respective, on both sides of the board, and connect them such a manner as to avoid small islands.
RCV56HCF PCI/CardBus Modem Designer’s Guide 4.1.8 Telephone and Local Handset Interface 1. Place common mode chokes in series with Tip and Ring for each connector. 2. Decouple the telephone line cables at the telephone line jacks. Typically, use a combination of series inductors, common mode chokes, and shunt capacitors. Methods to decouple telephone lines are similar to decoupling power lines, however, telephone line decoupling may be more difficult and deserves additional attention.
