Three Steps to Minimize Jitter in Gbps System Designs New Post

The challenge of clock jitter—which adversely impacts high-speed protocols such as Ethernet, PCI Express®, and USB 3.0—is becoming more significant as next-generation protocols look to deliver data rates at hundreds of gigabits per second (Gbps). Understanding three key points can help you achieve success against jitter in your next design.

Understanding the Demands on Hall Sensors for Automotive Applications

The demand for compact, accurate position sensors in automotive applications will grow substantially to $1.6 billion by 2026, in line with the growth in electric vehicles (Figure 1). These sensors track the rotor’s position inside the motor responsible for traction, power steering, and windows; ensuring control and safety coverage.

Simplify Your Embedded Designs Using I²C I/O Expanders

The I²C two-wire bus is still as popular today as when Philips originally invented it in 1982. Initially operating at 100KHz, the latest incarnation, version 7 (2021) Ultra-Fast-mode (UFm), now clocks at 5MHz—making it fast enough for most medium-speed peripherals, including digital I/O, GPIO, keyboards, keypads, and sensors.

Use a ReDriver or ReTimer for Longer and Thinner USB, USB Type-C, and DP Cables

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).

Plug-and-Play USB Charging Controller Makes Charging of Battery-Powered Devices Seamless

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.
