A connector, which is a passive product, is a component that provides a function of "connection" by receiving a part of the transmission margin in the concept of "signal integrity". With the exception of cases where the "share" of each part is defined by standards, etc., the exact characteristics required will vary depending on the construction of the customer's system. Ultimately, after verification using simulations and detailed data using a characteristic model, we will evaluate the actual product and then use it. In other words, except for standard products, the expression "** Gbps compatible connector" is not necessarily accurate. On the other hand, we understand that information such as "corresponding data rate" is extremely superior, even if it is only to some extent as a guideline, at the customer's initial examination stage in the introduction department. Therefore, IRISO has defined the "corresponding data rate" as a reference value to be recommended based on the customer's support experience so far and the evaluation / design performance of high frequency products, and has started to assign it to each product group. . In this regard, we have the following points in mind.
The data rate definition was performed with the most requested differential 100Ω, and was defined based on the mixed-mode S-parameters, which are the most popular parameters for passive components for high-speed transmission. In addition, because it depends on the customer's usage environment, crosstalk is not taken into account, and a single lane is defined. To avoid complication, the definition is based only on differential transmission and reflection characteristics. As a general rule, we use products that are mounted on our own printed circuit board, including soldered parts to the circuit board.
(For crosstalk and common mode conversion, we also provide individual data and conduct evaluations, so please contact us.)
The pass characteristics required for transmission lines are actually various due to processing such as emphasis and equalizing, and there are various discussions on harmonics (transmission margin vs. noise source, etc.). Therefore, our definition is easy to understand, and based on the basics, in NRZ transmission, it is -3 dB or less at the Nyquist frequency (Data Rate/2), which is the main frequency, and has sufficient linearity.
Reflection properties must be considered in terms of "noise generation" as well as signal transmission. Therefore, according to our company's regulations, in addition to not exceeding -15 dB at the Nyquist frequency, it is up to 1.5 times the Nyquist frequency (75% of Data Rate = right figure), which is calculated to cover the main spectrum in NRZ random transmission. -10dB = electric power, and it is stipulated that it should not exceed 10%.
This is a stricter regulation than recent transmission standards, such as PCIe CEM after Gen3.
The recommended supported data rate is the case that satisfies both the transmission and reflection characteristics described above, that is, the "severest" data rate required by each. As a matter of fact, most Board to Board Connectors have stricter reflection characteristics and transmission characteristics that are far superior (low loss) to the recommended data rate standards shown.
In addition, if there is compliance with various standards (ex. PCIe GEN3.0), it may be listed together, and there may be a gap with the recommended data rate. Even if the recommended data rate in our standard is lower than the standard transmission speed, it can be used because it satisfies the required performance.
