This whiteboard video presents a brief overview comparing the evolution of PCI Express data rates through five generations versus that of the common clock jitter specifications.

Renesas's chief PCIe system architect explains how to derive separate reference clock jitter limits from the PCI Express Gen4 and Gen5 specifications.

The IDT PhiClock™ 9FGV100x PCIe Gen 4 clock generators combine space savings, high performance and low power in a single, easy-to-use solution. All PhiClock PCIe reference clock devices integrate crystal load capacitors and offer an optional integrated crystal to simplify designs and save board space. When configured with HCSL outputs for PCIe applications, PhiClock products integrate the output termination resistors, further reducing board space. Extremely small 3 x 3 mm and 4 x 4 mm packages complement the integration for maximum space savings. The programmable PhiClock clock generators combine outstanding PCIe Gen4 performance and outstanding Ethernet performance with phase jitter as low as 225fs rms at 156.25MHz (12k-20M). Extremely low power consumption (as low as 100 mW at 1.8V) allows placement closer to high-power components, which also reduces board space requirements.

A detailed overview of IDT's full-featured PCI Express (PCIe) clock and timing solutions. The presentation addresses PCIe Gen 1, Gen 2, Gen 3, and Gen 4 architectures and how IDT's industry-leading solutions provide all the functions, features, and performance required by the application.

This is the first video in our PCIe series. In this video, we define PCIe architectures, focusing on common and separate clock architectures. Watch the rest of the video series below where Ron will cover the impact of different timing architectures.

In this episode, Ron Wade from IDT (acquired by Renesas) explains PCIe common clocking and its impact on timing solutions. Learn about using a single clock source, fan-out buffers, and the considerations for spread spectrum and non-spread spectrum clocking in PCIe systems.

In this video, we explore PCIe with separate reference clocks and the effects of clock selection. Learn how separate reference clocks work and their impact on system performance and stability.

This video provides a high-level overview of Separate Reference Clock with Independent Spread (SRIS) architectures for PCI Express systems, additional performance requirements that this clocking architecture imposes on the reference clocks, and some system implications encountered trying to implement the architecture.

IDT (acquired by Renesas) engineer provides a brief tutorial describing the main differences between standard HCSL and low-power HCSL (LP-HCSL).
