Abstract: Application Note 321 provides an example circuit for interfacing the Dallas Semiconductor/Maxim DS2152 or DS2154 single chip tranceivers (SCTs) to the IGT ALL1 SAR (WAC-021-C). Interconnections between the DS2152 or DS2154 and the IGT WAC-021-C are shown in Figure 1. Figure 1. Transceiver to WAC-021-C PCM interface. In the circuit shown above the framer outputs a multi-frame synchronization pulse on TSYNC. The signal drivers both TL_FSYNC and TL_MSYNC of the WAC-021-C. TL_FSYNC does not need to be driven at every frame boundary. TSYNC may be programmed as an input if the user wishes to define multiframe boundaries or slave several devices to the same multi-frame/frame boundary. Notes: The RSYNC and TSYNC pins on the DS2152, DS2154 are programmed as multiframe outputs. Use default signaling mode on WAC-021-C. Elastic Stores on DS2152, DS2154 are disabled. The signal TCLK may be derived from RCLK of the DS2152, DS2154. 相关型号   APP 321: May 08, 2001 DS2152 增强型T1单芯片收发器 完整的数据资料 (PDF, 1.3MB) 免费样品 DS2154 增强型E1单芯片收发器 完整的数据资料 (PDF, 1MB) 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 (24kB)  AN321, AN 321, APP321, Appnote321, Appnote 321
