SmartHSF Modem Device Set
The Conexant SmartHSF Host-Processed (SoftK56
TM
)
V.90 PCI Modem Device Family with SmartDAA technology
supports analog data up to 56 KBps, analog fax to 14.4 KBps,
TAM, and PCI Bus/Mini PCI host interface operation. In addition,
the device set optionally supports cellular phone interface
(PDC high speed/PDC packet data, PHS data, CDMA/CDMA
Packet data, GSM data) or voice/speakerphone. These modem
devices meet the size and power requirements of the mobile
environment. The modem operates with PSTN telephone lines
in the U.S./Japan/Canada and, optionally, worldwide. Optional
cellular interface supports Japanese Personal Digital Cellular
(PDC) and Personal Handyphone System (PHS) phones, Global
System for Mobile Communications (GSM) phones, and cdmaOne
(IS-95A/IS-95B) phones. Modem and cellular data protocol
software is provided.
Conexant’s SmartDAA proprietary technology eliminates the need
for a costly line transformer, relays, and opto-isolators typically
used in discrete Data Access Arrangement (DAA) implementations.
The SmartDAA architecture also simplifies product implementation
by eliminating the need for country-specific board configurations
enabling worldwide homologation of a single modem board design.
The SmartHSF device set, consisting of a CX11242 HSD in a 100-pin
TQFP and a CX20463 SmartDAA LSD in a 32-pin TQFP, supports
data/fax/TAM operation with host software-based digital signal
processing and cell phone/DAA/telephone line interface functions.
The optional CX20437 VC, in a 32-pin TQFP, supports voice/FDSP
operation with interfaces to a microphone, speaker, and telephone
handset/headset. Because some cellular interface signals and
CX20437 VC interface signals share the same CX11250 HSD pins,
speakerphone configuration does not support the cellular interface.
In V.90 data mode, the modem can receive data at speeds up to
56 KBps from a digitally connected V.90 compatible central site
modem. In this mode, the modem can transmit data at speeds
up to V.34 rates.
In V.34 data mode, the modem operates at line speeds up to 33.6
KBps. When applicable, error correction (V.42/MNP 2-4) and data
compression (V.42 bis/MNP 5) maximize data transfer integrity

Note. Two memory configurations are possible:
a.) 256K x 8 ROM/FLASH + 128K x 8 RAM (support and download)
b.) 128K x 8 ROM/FLASH + 32K x 8 RAMª
Note: For Low Power applications please call us for information, the RC56LD
family is suitable for PCMCIA/PC card applications.
ª Note: New controllers with internal 32K x 8 RAM are available therefore
reducing chipcount and PCB area.
