USB, USB Type-C®, and DisplayPort™ (DP) cables have become so ubiquitous as to even be purchased in low-cost convenience stores. However, while two individual cables may appear identical to the naked eye, they can differ considerably in the quality of performance they provide. Low cost can mean low quality, and alongside instances where cheap cables have caused electronic equipment to malfunction or have corrupted data, they typically cause poor picture quality or slow down the rate of data transfer to well below the multi-gigabit bandwidth offered by the latest USB specification (USB 4).
Tag: USB Type-C
In the not-too-distant past, it seemed like every electronic device had its own custom power supply, cable, and interface (Figure 1). USB Type-C® (or USB-C®), which implements the USB power delivery (USB-PD) specification, was supposed to solve this problem by introducing a single standard interface that all devices could use.
Highly integrated solutions for USB 3.2 data switching, USB Power Delivery and USB Battery Charging control, and transient protection help designers unleash the full potential of the USB Type-C interface.
USB Type-C: Everything you need to know about delivering high-speed serial connectivity in your devices
As well as being faster and able to deliver more power than its predecessors, USB Type‐C® makes some outwardly noticeable changes to this ubiquitous connectivity standard. For one, there’s a new reversible connector, which isn’t keyed so can be plugged into a port either way up. Secondly, USB Type‐C will see the same connectors used on both ends of the cable.
With its “insert either way” simplicity and legacy channel transport, Type-C is the last connector a user will ever need. But the burden’s now on the designer to understand Type-C.
Two sets of dynamics are on a collision course making an often overlooked technical detail—signal integrity on PCBs, cables, connectors, and IC chip sets—more important than ever. When clocks and switching speeds were in the hundreds of megahertz, digital signals implemented in standards like 10/100 Ethernet, USB 2.0, SCSI, PCI and others behaved as expected and systems functioned per spec.
