摘要：本应用笔记介绍如何DS2141A ， DS2143 ， DS2151 ， DS2153接口的西门子PEB2045 。这说明还显示的是不同的引脚接口的PEB2045的波形和时序图。Maxim > App Notes > COMMUNICATIONS CIRCUITS TELECOM Keywords: DS2141A, DS2143, DS2151, DS2153, interface, Siemens, PEB2045, loop, loop-time May 08, 2001 APPLICATION NOTE 315 DS2141A, DS2143, DS2151, DS2153 Interfacing to the Siemens PEB2045 Abstract: This application note describes how the DS2141A, DS2143, DS2151, and DS2153 interface to the Siemens PEB2045. This note also shows waveforms and timing diagrams of different pins that are used for interfacing to the PEB2045. Notes: 1. The PEB2045 is operated in the 4 MHz standard configuration mode. 2. Gates #1 and #2 are used to condition the frame sync to meet the timing requirements of the PEB2045. 3. Both the transmit and receive elastic stores in the DS2141A, DS2151 are enabled; the DS2143, DS2153 only n……
