HCFL/56

V.90/K56flex     PC Card Device Sets

for Host-Controlled, Low Power Applications

Conexant HCFL/56 PC Card Device Sets support high-speed

analog data up to 56 kbps, 14.4 kbps fax, voice/TAM, analog

cellular direct connect, and speakerphone (optional) operation

(Table 1). The modem supports ITU-T V.90/K56flex, V.34 and

V.32bis data modulations and is designed to operate with dial-up

telephone lines in the U.S. and worldwide. Low profile, small

PQFP/TQFP packages and low voltage operation with low power

consumption make this device set ideal for laptop, notebook, and

palmtop applications.

The device set consists of a PCMCIA bus interface device (L5502-

11 PCMCIA BIF) in a 128-pin TQFP and a modem data pump

(MDP) in a 144-pin TQFP or 100-pin PQFP. Host modem software

is provided and the downloadable architecture allows updating of

MDP executable code.

The L5502-11 PCMCIA bus interface device supports two

peripheral channels, one channel for the modem and a second

channel for an optional user-defined function (Function 2).

In V.90/K56flex mode, the modem can receive data at speeds up

to 56 kbps from a digitally connected V.90- or K56flex-compatible

central site modem. Taking advantage of the PSTN, which is

primarily digital except for the client modem to central office local

loop, V.90/K56flex modems are ideal for applications such as

remote access to an Internet Service Provider (ISP), on-line

service, or corporate site. The modem can send data at speeds up

to V.34 rates.

In V.34 data mode, the modem operates at line speeds up to 33.6

kbps. Error correction (V.42/MNP 2-4) and data compression

(V.42bis/MNP 5) maximize data transfer integrity and boost

average data throughput. Non-error-correcting mode is also

supported.

In V.32bis mode, the modem operates at line speeds up to 14.4

kbps.

In voice/TAM mode, enhanced 2-bit or 4-bit per sample ADPCM

coding and decoding at 7200 Hz sample rate allows efficient digital

storage of voice/audio. This mode supports applications such as

digital telephone answering machine (TAM), voice annotation, and

recording from and playback to the telephone line.
