Broadband equipment supplier PMC-Sierra, Inc. (Santa Clara, Calif.) and fab-less semiconductor maker Vativ Technologies (San Diego, Calif.) announce collaboration to deliver interoperable framer/mapper and line interface unit (LIU) devices for next-generation voice and data communications.
The planned high density, multi-channel DS3 equipment line-card is claimed to be the industry's lowest power and highest performance framer/mapper and LIU.
Vativ Technologies focuses on DSP-based transceivers for wired communications, so it looks like this accord will be a natural fit for the company. Based on its experience developing DSP algorithms, high-speed digital VLSI, and analog IC components, the company already delivers CMOS chips for LAN, WAN, and SAN applications.
A Synergistic Combo
The combination of PMC-Sierra's existing ARROW, SUNI, and TEMUX framer/mapper product families, and Vativ's VTE3 DS3 LIUs offer a way to seamlessly upgrade existing infrastructures. A reference design is available that addresses metro transport, access, and core applications. The combined approach dissipates less than 3.5-W, about half the dissipation of competing approaches.
PMC-Sierra's existing Model PM5385 ARROW 12xETEC integrates twelve DS3/E3/STS-1E framers, and can map them into an OC-12 data stream. The ARROW 12xETEC can also be used to convert six DS3/E3 streams into STS-1E streams.
For their part, Vativ's VTE3 DS3/E3/STS-1E LIUs claim dramatic performance improvements over current legacy LIUs, due to a proprietary DSP-based transceiver architecture.
For example, the digital adaptive equalizer in the receiver enables a VTE3 device to recover DS3 signals over 3000 feet of coaxial cable, exceeding the standards requirement by over three times. Additionally, the device includes programmability of the transmit pulse shape.
A reference design and jointly published application note, demonstrating Vativ's VTE3 DS3/E3/STS1 LIU family with PMC-Sierra's family of framer/mapper devices, is available on-line
