卓联半导体公司新推出的VEC芯片288通道的ZL50212和256通道的ZL50211在容量、功耗、成本等方面再创多项纪录,每个语音通道的成本低至仅1美元,比同类产品的成本低约50％两款高密度器件配合128通道MT93L04VEC即可处理工作在44.7Mbps速度的全速DS3（数字信号3级）接口,还有以低成本提供最佳语音质量的低功耗32通道VEC芯片ZL50232。ZL50232是一款低成本,高性能VEC器件,适用于密度较低的语音处理设备,如PBX（用户专用交换机）、无线基站和IVR（交互式语音应答）系统。ZL50232可灵活地配置为提供64ms语音消除功能的32通道方式。或者提供128ms语音消除功能的16通道方式,或者两种方式的任意组合。ZL50212和ZL50211采用535脚BGA封装,ZL50232采用100脚LQFP或208脚LBGA封装。三款VEC芯片的功耗都仅有4.68mW每通道。几乎只有VEC模块的功耗的三分之一,为其他供应商VEC器件的六分之一。
Zarlink Semiconductor’s new VEC chip ZL50212 288-channel and ZL50211 256-channel ZL50211 capacity, power consumption, cost and more to create a number of records, each voice channel as low as only 1 US dollars, compared to the cost of similar products About 50% lower Both high-density devices work with the 128-channel MT93L04VEC to handle full-speed DS3 (Digital Signal Level 3) interfaces operating at 44.7Mbps and low-power 32-channel VEC chips that deliver the best voice quality at low cost ZL50232. The ZL50232 is a low cost, high performance VEC device for low density voice processing equipment such as PBXs (customer premises switches), wireless base stations and IVR (Interactive Voice Response) systems. The ZL50232 is a flexible 32-channel configuration that provides 64ms of speech cancellation. Or 16-channel mode that provides 128ms voice cancellation function, or any combination of the two modes. ZL50212 and ZL50211 535-pin BGA package, ZL50232 100-pin LQFP or 208-foot LBGA package. The power consumption of the three VEC chips is only 4.68mW per channel. Almost a third of the power consumption of the VEC module is one-sixth that of other vendor VEC devices.
