Abstract: This application note describes how the DS2141A, DS2143, DS2151, and DS2153 interface to the Mitel MT8980D. This note also shows waveforms and timing diagrams of different pins that are used for interfacing with MT8980D. Notes: The DS2141A and DS2151 are set up with both the receive and transmit elastic stores enabled; the DS2143 and DS2153 only need the receive side elastic store enabled. The RSYNC pin is programmed to be an input; the TSYNC pin is programmed to be an output on the DS2141A, DS2151 and an input on the DS2143, DS2153. The SYSCLK is set for 2.084 MHz operation. The elastic stores provide controlled slip operation. In "looped-timed" applications, close switch 1 and open switch 2. In applications that cannot handle controlled slips, close switches 1 and 4, and open switches 2 and 3. In DS2151 and DS2153 applications, the line interface function is included onboard the device. Timing between the devices is shown below: 相关型号   APP 313: May 07, 2001 DS2141A T1控制器 完整的数据资料 (PDF, 480kB) 免费样品 DS2143 E1控制器 完整的数据资料 (PDF, 568kB) 免费样品 自动更新 需要自动接收最新发布的应用笔记吗？请订阅EE-Mail™ (English only)。 我们期待您的反馈！ 喜欢？不喜欢？有待改善？或为我们提供建议？请与我们联系 — 我们将根据您的意见或建议改善我们的工作。 网页评价或提供建议   下载，PDF格式 (30kB)  AN313, AN 313, APP313, Appnote313, Appnote 313
