Octasic Expands its Voice Processing Product Line with New Devices

Octasic Semiconductor is enhancing its OCT6100 family with the introduction of lower power, and lower cost devices based on 130nm technology. The new OCT6100L, which enables voice quality enhancement for down to 4 channels, was developed in partnership with STMicroelectronics,

Octasic said that as echo cancellation moves from a standalone box to an internal embedded feature of gateway and switching equipment, designers are faced with increasing demands for lower power to meet their density targets, while improving quality. The new OCT6100L builds upon the proven success of the current OCT6100 devices, which now has over 15 million ports deployed, enabling carrier-class voice quality enhancement at a cost point for small equipment, such as IP based PBXs. It includes key features such as Octasic Music Protection, Acoustic Echo Control (AEC), Adaptive Noise Reduction (ANR), and extensive conferencing capabilities.

By lowering the core voltage from 1.8V to 1.2V, the OCT6100L cuts the power performance of the original device in half, to less than 1.5 mW per fully featured channel. The device is also perfectly suited to adding or enhancing echo cancellation of existing platforms providing a more cost effective solution for carriers.

The low power and space requirement of the solution provides the opportunity to retrofit existing equipments that require external echo cancellation with minimal re-design. Where previously this type of redesign would require a reduction in capacity to accommodate the boards required, a daughter board for an existing linecard now becomes an option, preserving the original configurations and density of the equipment.

OCT6100 family features

  • Up to 672 channels G.168-2002 echo cancellation

  • 128ms tail/channel (on all channel densities)

  • Octasic Music Protection

  • Acoustic Echo Control

  • Adaptive Noise Reduction

  • Extensive signaling tone detection and generation

  • Audio Conferencing with Voice Quality features

  • Large buffer playback capabilities

  • TFO solution available

  • Field upgradeable algorithm

  • Integrated debugging and monitoring

  • Compact size: 16mm x 16mm

Samples of the OCT6100L are currently available; Production quantities are planned for early 2006, with pricing under $0.50 per channel in volume quantities.
  • In May 2005, STMicroelectronics and Octasic announced a partnership to deliver a family of voice-over-packet (VoP) ICs. The solutions will be based on ST's 0.13-┬Ám and 90-nm semiconductor process technology and Octasic's designs for VoP and Voice Quality Enhancement (VQE), which includes technology for line and acoustic echo cancellation, noise reduction capabilities, vocoding and packetization.
