Intersil is combining its subscriber line interface circuits (SLICs) with digital signal processors (DSPs) from VoicePump, a subsidiary of DSP Group, for a new four-channel, voice-over-packet (VoP) development platform and reference design. The combination provides manufacturers of low-to-medium-density voice gateways and integrated access devices with a more cost-effective, short time-to-market system.
The reference design combines four compact Intersil HC55185 ringing SLICs in MLF package with VoicePump's programmable four-channel VP140 mixed-signal DSP. The VP140 is a member of VoicePump's VP100 family and is designed to integrate DSP Group's TeakLite DSP core with most of the circuitry needed to accommodate four packet-voice channels in a single processor. Intersil and VoicePump anticipate that their development platform will provide customers with a complete turnkey solution that shortens time-to-market and reduces engineering/design costs for VoP integrated access devices (IADs) used with voice over digital subscriber line (VoDSL), voice over Internet protocol (VoIP), or voice over broadband (VoB) technologies in general.
