IDT (Integrated Device Technology, Inc.), a leading communications IC company, and VoicePump, Inc., a wholly owned subsidiary of DSP Group, Inc., today announced a strategic partnership to deliver a voice-enabled asymmetric digital subscriber line (ADSL)

SANTA CLARA, Calif., March 11, 2002 - IDT (Integrated Device
Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, and
VoicePump, Inc., a wholly owned subsidiary of DSP Group, Inc. (Nasdaq:
DSPG), today announced a strategic partnership to deliver a voice-enabled
asymmetric digital subscriber line (ADSL) reference platform for customers
designing customer premises equipment (CPE). Jointly developed by IDT and
VoicePump, the reference platform enables customers to simplify their
design process, accelerating the product development and time-to-market
cycle for systems that support voice-over-Internet protocol (VoIP) or
voice-over-digital subscriber line (VoDSL) technologies.

There are few voice-enabled platforms in the gateway market today. The
combination of IDT's RC32355 integrated communications processor and
VoicePump's VP140 intelligent CODEC will enable customers to design a
cost-effective, flexible platform that supports both data-only gateways
and integrated access devices (IADs). As a two-chip solution, this single
system architecture approach maximizes software code reuse between several
end products, thereby improving time to market. Additionally, customers
are able to focus their engineering efforts on value-added features, thus
allowing product differentiation.

"VoicePump is partnering with industry-leading integrated
communications processor vendor IDT to provide a highly scalable IAD
platform that addresses support of data and voice traffic," said Cole
Erskine, VoicePump's chief technology officer. "The IDT and VoicePump
reference platform offers a solution that our shared customers can
integrate with confidence, knowing that the technologies are fully

The 79RP355V reference platform, consisting of IDT's 79RP355 gateway
reference design and VoicePump's VP140 evaluation board, incorporates
highly integrated hardware, as well as the necessary firmware for support
in the development of VoIP and VoDSL applications. The inclusion of
industry-standard input/output (I/O) interfaces on IDT's RC32355
integrated communications processor simplifies connectivity between the
wide area network (WAN), the local area network (LAN) and the voice
subsystem. The processor's high-performance central processing unit (CPU)
core enables value-added capabilities and services for differentiating the
end application, offering further system flexibility options and providing
an opportunity to add new features to deployed units in the field via
download over the network. VoicePump's VP140 intelligent CODEC performs
all of the voiceband processing functions required for support of voice
channels, including on-chip capabilities for speech compression, echo
cancellation and four-channel signaling.

"As a company focused on 'powering what's next,' IDT believes the
partnership with VoicePump will help us to be well positioned for the
emergence of VoDSL and VoIP technology," said Sandra Chang, strategic
alliance program manager for IDT's Internetworking Products Division.
"VoicePump's inclusion of digital signal processing (DSP) functionality
and traditional telephony circuitry, coupled with the availability of a
broad selection of commonly used voice algorithms, provides a low-cost
voice subsystem that can be implemented very quickly and efficiently as
part of our customers' designs."

IDT's RC32355 Integrated Communications

IDT's RC32355 integrated communications processor is a single-chip
solution optimized to address system bandwidth needs with an unprecedented
combination of performance, flexibility and integration. Targeted at the
CPE market, the RC32355 integrated communications processor is supported
by software and tools from market leaders of complementary technology,
like VoicePump, to provide a complete hardware and software solution for
designers of gateway system equipment.

With the introduction of the RC32355 integrated communications
processor, IDT is the first company to successfully integrate ATM,
Ethernet, USB and telephony interfaces with a high-performance
microprocessor core, while maintaining concurrent wire speed on all
interfaces. These capabilities offer designers increased flexibility to
meet the system requirements of the CPE market.

VoicePump's VP140

Announced in October 2000, VoicePump's VP140 series is designed to
integrate DSP Group's TeakLite® programmable DSP core with all requisite
peripherals to perform four packet voice channels on a single processor:
program/data memory, host processor interface, analog front end,
analog-to-digital and digital-to-analog converters.

The VP100 family also integrates the necessary DSP firmware to perform
a comprehensive range of DSP functions, including speech compression and
decompression, echo cancellation and associated telephony signaling
functions. This integrated silicon/software product offering is ideally
suited for use as the voiceband-processing engine of VoDSL IADs and VoIP
gateways for small and medium enterprises, as well as residences.

Pricing and Availability

The 79RP355V reference platform is sampling now, with full production
quantities from IDT available in June 2002. The reference platform is
priced at $5,000. Additional information about the RC32355 integrated
communications processor, associated reference boards, and other IDT
integrated processors can be found on IDT's Web site.
