  • 基于Multisim的高精度數字頻率計的設計和仿真

    數字頻率計是電工電子中常用的測量儀器,數字頻率計通過用輸入待測信號對一特定長度的信號進行計數,從而得出頻率并通過數碼管直觀的顯示出來。本文提出了一種與輸入同步的數字頻率計的設計,提高了頻率計的精度,設計采用Multisim軟件進行設計和仿真的過程,介紹了其工作原理,硬件電路設計和仿真的過程。設計采用了Multisim軟件進行設計和仿真,設計結果得到的驗證。Digital frequency counter is used to measure the frequency of a signal.It is common to use a multivibrator to generate a standard 1 second time base signal and count input signal gated by this signal.However,the asynchronous of this time base signal with input signal will bring errors.In this paper,a high precision frequency counter which use synchronized time base signal generator is proposed.This frequency counter is designed and simulated by Multisim tools and result is verified.

  • 高速串行Serdes信號的眼圖抖動測試

    隨著新研發單板上高速Serdes信號的增多,信號完整性測試顯的越來越重要,本文檔圍繞Serdes信號的眼圖抖動測試總結一些測試注意事項。新研發單板上高速Serdes信號速率高達2.45G,一些時鐘信號上升/下降沿達到400ps左右,必然需要測量Serdes信號的眼圖、抖動,在這里總結一些測試經驗和注意事項。UBPG1單板上有如下幾種高速數據SERDES信號:1.         GE SERDES接口(SGMII接口標準)2.         AIF SERDES接口(CPRI接口標準)3.         IQ SERDES接口(類CPRI接口標準,自定義幀格式)4.         光口 SERDES接口(CPRI接口標準)對于SERDES信號,其信號電氣特性由IEEE協議規定,在協議中會給出相應的眼圖測試模板及抖動指標,部分芯片廠家會在DATASHEET中給出單獨的眼圖測試模板及抖動指標(一般會比協議要求的更寬松)。UBPG1單板上的SERDES接口按電氣特性分有兩種,一種是SGMII接口(用1000-BASE-CX模板,IEEE協議39節);一種是CPRI接口(用XAUI模板,IEEE協議49節)。
