Voice echo canceller chips

20 October 2004 Telecoms, Datacoms, Wireless, IoT

Zarlink Semiconductor has introduced two new VEC (voice echo canceller) devices with advanced features that can help ensure carrier-grade voice quality for packet-based and cellular networking equipment operating in high-noise environments.

The 256-channel ZL38070 and 32-channel ZL38065 VECs are high-capacity, low-power devices that use patented NLP (non-linear processing) software to deliver improved noise-matching techniques. In addition, the devices' programmable threshold and convergence speeds improve double-talk performance. The VECs are targeted at IP-PBXs (Internet Protocol-Private Branch Exchanges), 3G wireless base stations, mobile switching centres and other equipment operating in noisy settings.

The ZL38065 device comes in a 100-pin LQFP or 208-ball LBGA while the ZL38070 comes in a 535-ball PBGA.
