Skew Spec. of High Speed Interfaces

高速介面的相位偏移規格

總結幾個目前常用並且明文規定的高速介面的相位偏移規格：

單位間隔（Unit Interval, UI）是數據傳輸中的一個基本單位時間，用來表示信號在傳輸過程中的每個比特或符號的時間長度。它是高速串行接口設計中的關鍵參數，用於計算抖動、偏移（skew）等時間參數。UI 的計算方法如下：

 Unit Interval (UI)

UI 是每個比特或符號的時間間隔，其計算方法是數據速率的倒數。

公式：

$\text{UI }= \frac{\mathrm{1\; / }}{\text{數據速率}}$

數據速率通常以 Giga Transfers per second (GT/s) 或 Giga Baud (GBd) 表示，這些單位代表每秒傳輸的比特或符號的數量。

Skew Spec. of High Speed Interfaces

Summarize the skew specifications of several currently commonly used and clearly specified high-speed interfaces:

The Unit Interval (UI) is a fundamental unit of time in data transmission, used to represent the duration of each bit or symbol during signal transmission. It is a crucial parameter in the design of high-speed serial interfaces, used for calculating jitter, skew, and other timing parameters. The calculation method for UI is as follows:

 (UI)

UI is the time interval for each bit or symbol, calculated as the reciprocal of the data rate.

Formula:

$\text{UI }= \frac{\mathrm{1\; / }}{\text{Data Rate}}$

The data rate is typically expressed in Giga Transfers per second (GT/s) or Giga Baud (GBd), which represent the number of bits or symbols transmitted per second.
