Abstract: Application Note 354 provides a logical diagram of the clock map of the Dallas Semiconductor/Maxim DS2154 and DS2152 single chip transceivers (SCTs). Figure 1 logically describes the clock map of the DS2152 and DS2154 Single Chip Transceivers. Although there is only one Jitter Attenuator, which can be placed in the receive or transmit path, two are shown for simplification and clarity. Figure 1. Clock map. Notes The PAYLOAD loopback switch is not included on the DS2154 . LTCA = Long Term Clock Average   RLB = Remote LoopBack JAS = Jitter Attenuator Select   FLB = Framer LoopBack DJA = Disable Jitter Attenuator   PLB = Payload LoopBack RCL = Receive Carrier Loss   LLB = Local Loopback LOTCMC = Loss Of Transmit Clock Mux Control RXCLK = Recovered clock from LIU TXCLK = Transmit rate clock for LIU 相关型号   APP 354: May 16, 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 (32kB)  AN354, AN 354, APP354, Appnote354, Appnote 354
