Voicepump Selects Agere Systems' SLIC Chips for Use on Reference Designs for Integrated Access Devices

ALLENTOWN, Pa. -- Agere Systems (NYSE: AGR.A) today announced that VoicePump, Inc., has chosen its subscriber line interface circuit (SLIC) communications chips for use on a new Voice over Digital Subscriber Line (VoDSL) integrated access device (IAD) reference design. The reference design is targeted for use in small office/home office VoDSL and Voice over Internet Protocol (VoIP) IADs and other types of Voice over Broadband customer premises equipment.

VoicePump, a wholly owned subsidiary of DSP Group, Inc. (NASDAQ: DSPG), currently uses Agere's 5 volt L8560 SLIC chip for existing reference designs and is evaluating Agere's smaller and lower-power 3.3 volt L9214, L9215, and L9216 SLIC chips for next-generation IAD and voice gateway reference designs. Agere's low-voltage SLICs, together with VoicePump's 3.3 volt VP140 packet voice processor, help reduce power consumption, external component count, and cost.

"Agere's SLIC chips are very low-power devices that still meet the price target of the most cost-sensitive customer premises equipment manufacturers," said Cole Erskine, chief technical officer with VoicePump. "Agere's micro lead chip carrier packaging, in conjunction with VoicePump's integrated sigma-delta modulation converters and analog front-end, greatly reduce overall board space requirements."

Agere's L8560 chip resides on the reference board with VoicePump's VP140, which is a complete voiceband processing solution for IADs supporting four derived voice lines. Agere's SLIC chips provide the interface between the VoicePump VP140's analog front end and a telephone user's existing, standard telephone set. The VoDSL reference design also incorporates NEC Corporation's mPD98501 Network Controller, a 100 Megahertz device with Asynchronous Transfer Mode Segmentation and Reassembly, Universal Serial Bus, and two ports of 10/100 Ethernet. VoicePump will display the reference design at the SuperComm 2001 event in Atlanta, Ga., June 3-7 in booth 9041.

"By integrating Agere's SLIC chips in VoicePump's reference design, we are creating a higher performance, more economical solution for integrated access device manufacturers," said Tom Marihart, strategic marketing manager with Agere Systems.

Agere's standard L9214, L9215, and L9216 are priced in the range of $3.00 in quantities of 100,000. VoicePump's VP140, complete with embedded DSP firmware for VoDSL applications, is available for $15 in quantities of 10,000.
