High-speed Transmission Trend

This article explains the increasing speed trend in transmission standards. We're assuming that you have a chance to design your products based on transmission standards in order to achieve high-speed transmission. Please refer to the following information as basic knowledge for designing devices.

The transmission speeds of PCs and smartphones have been ever increasing recently. This is because the amount of information processed by devices has been increasing with the widespread use of the Internet.
Accordingly, various types of transmission standards, including USB standards known well by everyone, have been continually established one after another. (Fig. 1)

Fig. 1) Release timing of transmission standards vs Transmission speeds

As seen in Fig. 1, the support of the standards up to the transmission speed of 10 Gbps* (Note 1) has, at present, been started.

* Note 1: 10 Gbps (Giga Bits Per Second) = Transmission speed that allows the transmission of 10 Giga-bit data per second.

The transmission speeds of major transmission standards are summarized in Table 1 below.

Table1) Overview of major transmission standards

We assume you understand that each of transmission standards, applicable to a variety of applications, shows an increasing speed trend.

Consequently, as the speeds of data transmission between base boards in devices increase, it has become necessary for components including connectors to support high-speed transmission.

What types of measures are specifically required to be taken for connectors to allow high-speed transmission?

  1. Impedance matching
  2. Antinoise measures

The above two main points should be mentioned.

Panasonic provides a lineup of two product series that meet these high-speed transmission needs.
One series is the Y4BH FPC connectors capable of impedance matching.
Another series is the P4S shield type narrow pitch connectors provided with antinoise measures.

There may be readers who feel anxiety about difficult terms like impedance and noise.

Since the next and subsequent courses will explain these terms, please feel at ease.


How were the above explanations? This course explained the subject of the increasing speed trend in transmission standards. Please make effective use of these explanations as basic knowledge for designing devices.
