DSP Group, Inc. was an American company that manufactured chipsets for VoIP, multimedia, and digital cordless applications. Founded in 1987 with headquarters in San Jose, California, DSP Group employed over 400 people at three US sites and offices in Germany, Scotland, Israel, India, Hong Kong and Japan until it was acquired by Synaptics.
DSP Group was founded in 1987 by Davidi Gilo, who served as the company's CEO and chairman until 1993. [1]
DSP Group developed the world's first telephony answering device (TAD) speech processor in 1989. [2] The company entered the digital cordless industry with the acquisition of Advanced Micro Devices' (AMD) 900 MHz technology in 1999, and the subsequent development of 900 MHz narrow-band cordless and 2.4 GHz multi-handset technology. [3]
In 1993 one of the company's co-founder and its CTO Shabtai Adlersberg started a new company AudioCodes, with the initial investment provided by the DSP Group. AudioCodes become a provider of VoIP technology, and had an initial public offering on the NASDAQ in 1999. In 2004 DSP Group sold all its holdings in AudioCodes making a significant profit on its initial investment. [4]
In 1994 the DSP Group had an initial public offering on the NASDAQ.
In 1996 DSP Group spun off its cellular chip design and development division into a new company called DSP Communications (DSPC). [5] DSP Communications had an initial public offering on the NASDAQ the same year. In 1999 Intel bought DSP Communications for US$1.6 billion. [6]
In November 2002, DSP's IP licensing division and the Irish company Parthus Technologies Plc were merged to form a new company called CEVA, Inc. [7]
DSP Group entered into the multimedia communications sector with the acquisition of Teleman Multimedia in 2003. [8] Incorporating VoIP and Wi-Fi technologies obtained through the acquisition of VoicePump and Bermai, DSP Group entered the residential multimedia communications over broadband market with the 2006 development of a chipset integrating DECT and Wi-Fi technologies with an application processor. DSP Group acquired NXP Semiconductors' cordless and VoIP terminals business in 2007. [9]
On 30 August 2021 it was announced San Jose, California-based developer of human interface (HMI) hardware and software Synaptics will acquire the company. [10]
DSP Group provides integrated circuits for residential communications products in three areas: connected multimedia screens, VoIP cordless phones, and digital cordless products.
Afiliations include:
Digital Enhanced Cordless Telecommunications, usually known by the acronym DECT, is a standard primarily used for creating cordless telephone systems. It originated in Europe, where it is the common standard, replacing earlier cordless phone standards, such as 900 MHz CT1 and CT2.
Freescale Semiconductor, Inc. was an American semiconductor manufacturer. It was created by the divestiture of the Semiconductor Products Sector of Motorola in 2004. Freescale focused their integrated circuit products on the automotive, embedded and communications markets. It was bought by a private investor group in 2006, and subsequently merged into NXP Semiconductors in 2015.
The Freebox is an ADSL-VDSL-FTTH modem and a set-top box that the French Internet service provider named Free provides to its DSL-FTTH subscribers.
Synaptics is a publicly owned San Jose, California-based developer of human interface (HMI) hardware and software, including touchpads for computer laptops; touch, display driver, and fingerprint biometrics technology for smartphones; and touch, video and far-field voice technology for smart home devices and automotives. Synaptics sells its products to original equipment manufacturers (OEMs) and display manufacturers.
Conexant Systems, Inc. was an American-based software developer and fabless semiconductor company that developed technology for voice and audio processing, imaging and modems. The company began as a division of Rockwell International, before being spun off as a public company. Conexant itself then spun off several business units, creating independent public companies which included Skyworks Solutions and Mindspeed Technologies.
HomeRF was a wireless networking specification for home devices. It was developed in 1998 by the Home Radio Frequency Working Group, a consortium of mobile wireless companies that included Proxim Wireless, Intel, Siemens AG, Motorola, Philips and more than 100 other companies.
VLSI Technology, Inc., was an American company that designed and manufactured custom and semi-custom integrated circuits (ICs). The company was based in Silicon Valley, with headquarters at 1109 McKay Drive in San Jose. Along with LSI Logic, VLSI Technology defined the leading edge of the application-specific integrated circuit (ASIC) business, which accelerated the push of powerful embedded systems into affordable products.
A VoIP phone or IP phone uses voice over IP technologies for placing and transmitting telephone calls over an IP network, such as the Internet. This is in contrast to a standard phone which uses the traditional public switched telephone network (PSTN).
VocalTec Communications Inc. is an Israeli telecom equipment provider. The company was founded in 1985 by Alon Cohen and Lior Haramaty, who patented the first Voice over IP audio transceiver. VocalTec has supplied major customers such as Deutsche Telekom, Telecom Italia, and many others.
Qualcomm Atheros is a developer of semiconductor chips for network communications, particularly wireless chipsets. The company was founded under the name T-Span Systems in 1998 by experts in signal processing and VLSI design from Stanford University, the University of California, Berkeley, and private industry. The company was renamed Atheros Communications in 2000 and it completed an initial public offering in February 2004, trading on the NASDAQ under the symbol ATHR.
Generic Access Network (GAN) is a protocol that extends mobile voice, data and multimedia applications over IP networks. Unlicensed Mobile Access (UMA) is the commercial name used by mobile carriers for external IP access into their core networks. The latest generation system is named Wi-Fi calling or VoWiFi by a number of handset manufacturers, including Apple and Samsung, a move that is being mirrored by carriers like T-Mobile US and Vodafone. The service is dependent on IMS, IPsec, IWLAN and ePDG.
Poly, formerly Polycom, a part of HP Inc., is an American multinational corporation that develops video, voice and content collaboration and communication technology.
Mobile VoIP or simply mVoIP is an extension of mobility to a voice over IP network. Two types of communication are generally supported: cordless telephones using DECT or PCS protocols for short range or campus communications where all base stations are linked into the same LAN, and wider area communications using 3G or 4G protocols.

RF CMOS is a metal–oxide–semiconductor (MOS) integrated circuit (IC) technology that integrates radio-frequency (RF), analog and digital electronics on a mixed-signal CMOS RF circuit chip. It is widely used in modern wireless telecommunications, such as cellular networks, Bluetooth, Wi-Fi, GPS receivers, broadcasting, vehicular communication systems, and the radio transceivers in all modern mobile phones and wireless networking devices. RF CMOS technology was pioneered by Pakistani engineer Asad Ali Abidi at UCLA during the late 1980s to early 1990s, and helped bring about the wireless revolution with the introduction of digital signal processing in wireless communications. The development and design of RF CMOS devices was enabled by van der Ziel's FET RF noise model, which was published in the early 1960s and remained largely forgotten until the 1990s.
