ZL79124数据手册集成电路（IC）的音频专用规格书PDF

描述 Description

The ZL79124 Next Generation VoiceEdge Control Processor (VCP) is a second generation platform that delivers enhanced call control, self-test and line test capabilities. This latest processor works with Microchip NGCC devices using its SPI interface(s), PCM port(s) and GPIO. The ZL79124 device provides the same integrated line-testing and feature-set as the Le79112 device, plus additional capabilities such as 4 channels of simultaneous line testing and 72 channels of improved POTS control. This product enables the design of a low-cost, highperformance, fully software programmable line interface with worldwide applicability. All AC, DC, and signaling parameters are programmable. The ZL79124 device is provided with extensive software and support, through the LineCare™ software suite, enabling the designer to develop a fully programmable solution in the least amount of time.
