The offer exceeds the $14 per share offer made last week by EDA rival Mentor Graphics Corp., and precedes the Quickturn sharholder meeting scheduled for this Friday (Jan. 8), at which Quickturn shareholders are expected to vote on a slate of directors backed by Mentor.

The ISD-T360 series of ICs contains all voice signal processing and peripheral functions needed for message handling on one chip, according to ISD (San Jose, Calif.). A key application for the chip family, the company said, is cordless phones with advanced answering machine functions or otherfeatures, such as duplex speaker phone operations or multi-country caller ID.

The ISD-T360 is the first of a series of high-performance DSPs, based on our next level platform,” said Avi Barel, vice president and general manager of ISD Israel. The family includes interfaces to multiple coder-decoders (codecs). The processors also have interfaces for pulse code modulation (PCM).

The series is priced from $3.50 each to $5 in quantities of 10,000 units. The parts will become available in the first quarter of 1999.

NORWOOD, Mass. — Analog Devices Inc. calls the Winmodem” AD1806 chip, introduced last week, the most integrated modem part it's ever built. The single-chip data pump builds PCI-based controller-less modems for data, fax and voice transmission. Built to 3Com Corp.'s specifications, it is expected to account for more than 40 percent of the modems 3Com sells this year.

ADI said it believes the AD1806 is the first single-chip V.90 56-kbits/second modem to include a PCI interface, POTS line and handset codecs, a 16-bit DSP and memory. The device also includes a separate D/A converter and low-power amplifier to drive the modem monitor speaker, said Maury Wood, modem product line manager for ADI, based here.

The DSP core in the modem chip is a 34-Mips version of the ADSP2181, said Wood. The ADSP2181 is a communications device known for its large 80 kbytes of on-chip memory, configured as 16k of 24-bit words of program RAM, and 16k of 16-bit words of data RAM.

By incorporating the data converters on the same chip with the DSP and memory, ADI believes its Winmodem offers higher levels of integration than V.90 products from competitors Lucent Technologies and Conexant (formerly Rockwell Semiconductor). Most significant, perhaps, is that the AD1806 single-chip modem displaces some of the DSPs supplied up to now by Texas Instruments.

There is no question that TI has considerable strength in DSP, and that 3Com will continue to buy a lot of DSPs from them,” said Wood. The TI modem chip includes hardware communications port controllers, which lend themselves to outboard modem applications, but not the phone line and handset codecs.

The main advantage of integrating the codecs,” said Wood, is that it allows 3Com to reduce its costs by lowering its bill of materials.” Price pressures are pushing modem makers toward controller-less” designs, and 90 percent of PCI modems will likely use software flow control, he said.

Symbol designs and manufactures bar-code based data transaction systems, including hand-held information appliances, and radio frequency communication devices used in retailing, transportation, health care, and other industries.

After initial production is completed in Maine, volume manufacturing is expected to be moved to one of SCI's plants in Mexico. SCI has operations in Mexico City, Guadalajara, and Apadaco, Mexico.

Analysts project that Symbol will report revenue of approximately $1 billion for 1998.

Thomas Hopkins, an analyst with Bear, Stearns, & Co. Inc., said SCI's contract with Symbol is expected to add in excess of $100 million to SCI's annual revenue.

Lucent Technologies Inc.'s Microelectronics Group has introduced a chipset the company believes will significantly reduce the price of digital spread-spectrum-based cordless telephones.
