SAN DIEGO -- Vativ Technologies, a leading-edge developer of DSP-based, high-performance wired communication ICs, today announced a multi-channel line interface (LIU) solution that significantly advances the technology and physical layer performance for T3/E3/STS-1 equipment line cards.

The VTE3-n is available in one- to six-channel versions in an extremely compact 12 x 12mm BGA package. Operating at 75mW per channel, the six-channel device dissipates less than half a watt in full-duplex operation. It achieves dramatic performance improvements over current “legacy” LIUs due to incorporation of Vativ’s proprietary DSP-based transceiver architecture. For example, the digital adaptive equalizer in the receiver enables the VTE3 device to recover DS3 signals over 3000 feet of coaxial cable (Type 734/738), exceeding the standards requirement by over 3x (see attached PDF). Additionally, the transmit data path includes programmability of the transmit pulse shape which results in added flexibility for system designers. This best-of-breed product boosts the design robustness for building the multi-service provisioning platforms (MSPP) that are being designed to meet today’s escalating subscriber bandwidth demands. The added benefit of very low power dissipation enables increased port density designs without substantially increasing platform power budgets.

“Our breakthrough technical advances incorporated in the VTE3 device offer our customers the industry’s highest performance, lowest power, and smallest package T3/E3/STS1 LIU solution,” said Sreen Raghavan, president and CEO of Vativ Technologies. “As a direct result of our patent-pending DSP technology, we are able to provide T3/E3 line card designers greater system design margins and improved flexibility to increase port densities.”

“We have been sampling the VTE3-6 evaluation kit to several customers over the past few months and are pleased with the very favorable feedback from these customers,” said Paul Van Eynde, Vice President of Sales.
