2所示， 本 同步方法的多 BT 包括 1 BT ， 包括依次相連的 GP 101 GP 接收 102、 相 103和 特 104。 BT 功能力同步GP ， 本地同步 ， 將本地同步 分別 2 BT 作力同步 參考。 As shown in 2, the multi-BT of this synchronization method includes 1 BT , including GP 101 GP receiving 102, phase 103 and special 104 connected in sequence. BT function force synchronization GP, local synchronization, local synchronization 2 BT force synchronization reference.
GP 101， 是 BT 的外部配置 各， 于接收GP 的GP ， BT 內部的GP 接收 102 GP 接收 102， 于接收 解析GP 101 的GP ，  GP 101, which is an external configuration of BT, is received by the GP of the GP, and the GP inside the BT receives the 102 GP reception 102, and receives the GP of the GP 101.

Due to the loss of GP external shadows, BT's phase 103 needs a fixed odove capability, which is generally a local high-altitude (Ove-co o edCysa Osc ao, OCXO) temperature quartz (Tempe ae Compe sae Cysa Osc ao, TCXO) provides odove capability. Phase 103 has 2 schemes. It is an ed ogammabe Gae ay (FPGA) composable device (Compex ogammabe ogc evc (CP)) And local high-phase operation, phase difference and advance, the processor, the processor uses the software algorithm phase to control the character, and then the model ( g ao- aog Co ve e , A ) will control the control into a similar, control local high Hugh's, and formed phase. Another use of built-in phase, direct frequency synthesis (ec ga Sy hesze,) AC's Xiang Linsi, local high-off and AC provide work, than A company's A g549 A g548 and so on. Special 104 local synchronization is specific to the same form of BT, usually VC O to. Hugh ( , ) aoa Semco d co company's g C176 (Texas s me s copo aed, T) 65 V 206 can function . At least BT (2 in BT, but BT is not limited to), including multiple BT in the system, the status of multiple BT is completely equal, and the internals are exactly the same. Including the special 106, the extension 107 phase 108 connected in sequence. BT needs to synchronize the synchronization of BT.
特 106 將接收到的信 特換成 于本 使用的 形式，通常 到 VC 的特 。 公司的 g C176 T 公司的 65 V 206等 都可以 功能。 延退 107 由可 輯器件 ， 目的是將 相 103的 到 相 108的 迷 段 造成的延退 。 果 BT 內部的 特 104 106 用的 定， 連接 BT 的 特 的外部 、長度 定， 那 延退就是可以 預 的 。例 相 103 到 特 104 同PCB( ed C c Bo d， 印制 路板)造成的信 延退 ， 特 104本身延退 22， 特 104 106 同 延退 3， 特 106本身延退 4, 特 106到延退 107 同 PCB造成 延退 5，延退 107到 相 108 同的PCB延退 6，那 +2+3+4+5+6, 作力延退 107所需 的 延退。由于 板材 FR4的PCB 上 速度接近光速的 1/2， 即 0． m/ s， 特 本身延退也多在 s， 在銅 中的 速度也是接近光速， 所以， 果 特 104 106 同的 較 ， 只有 ， 可以完全忽略 延退， 不需要 延退 果 很長， 比 十米， 則可以粗略的只 3 。 延退 精度視 統需求而定。  The special 106 replaces the received letter with the form used, usually to the VC. The company's g C176 T company's 65 V 206 can be functional. The extension 107 is an optional device that is designed to delay the phase 103 to the phase 108 segment. If the BT's internal special 104 106 is used to connect to the BT's special external and length, then the extension is predictable. Case 103 to special 104 with PCB ( ed C c Bo d, printed circuit board) caused by letter delay, special 104 itself extended 22, special 104 106 with extension 3, special 106 itself extended 4, special 106 To the extension of 107, the PCB caused the extension 5, and the extension of 107 to the phase 108 of the same PCB extension 6, that +2+3+4+5+6, the force required to extend the required extension of 107. Because the speed of the board FR4 on the PCB is close to 1/2 of the speed of light, that is, 0. m/ s, the special extension itself is also in s, the speed in copper is also close to the speed of light, so, the same as the 104 106, only, can completely ignore the extension, do not need to extend the fruit is very long, than ten M, you can only roughly 3. The delay accuracy depends on the system requirements.
