The 2-wire I²C bus is an incredibly useful way to add all kinds of low-speed I/O besides I²C while simplifying designs and trace routing.
Designers know that redrivers are an essential part of solving signal integrity challenges in gigabit systems. But at speeds up to 8 GT/s in PCI Express 3.0 systems, linear redrivers are needed to also comply with PCI-SIG specs and with chipset vendors’ datasheets.
Look around you at all the gadgets and appliances labeled as “smart” and you’ll find impressive integrated microcontrollers, SoCs and wireless connectivity inside. In an Internet of Things (IoT) age, consumers expect their home appliances to do more—and they indeed do.
Move over CANbus, PCI Express is the latest communications technology found in automotive infotainment.
Capable of 10 Gbps speeds and beyond, DisplayPort requires linear redrivers to achieve proper signal integrity with link training.
Clock jitter can adversely affect high-speed protocols such as Ethernet, PCI Express and USB 3.0. You can calm your system down knowing these three simple points.
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.
Want thinner or longer USB or HDMI cables? Turning them from passive to active is the only way to go.
PCIe Gen2 (Gen3 is still ramping up) is about as common on digital PCBs as is a terminal block or pin header. Nearly every CPU, MCU, fast peripheral, bus or nonvolatile (NV) memory sports PCIe. To connect all of these “dots” together requires a PCI Express switch or one of the creative variations thereof.
