Specifications

Internet to the desktop at V.90 speeds and is packed with features
such as Fax Class 1 support and telephone answering machine
functionality. SmartDAA technology reduces design costs by
eliminating many of the discrete devices that are needed for a
traditional discrete DAA. This allows modem designers to homologate
a single worldwide design, enabling a quicker time to market.
Modem reference kits are available to help OEM partners
accelerate their time to production.

Operating with a +5V power from the USB, this device set supports
applications in such designs as external USB modems. Downloadable
architecture allows updating of MDP executable code.
All models support remote audio recording and remote audio
playback over the telephone line interface using A-Law, µ-Law, or
linear coding at 8.0 KHz sample rate to support applications such as
digital TAM and voice annotation. The SP model supports position
independent, FDSP. Fax Group 3 send and receive rates are
supported up to 14.4 KBps with T.30 protocol. V.80 synchronous
access mode supports host-controlled communication protocols.
e.g., H.324 video conferencing.
A reference design kit in electronic form is available to minimize
