描述
The IDT5V41315 is a PCIe Gen1/2/3 clock synthesizer suitable for use in both Common-Clocked and Separate Reference clock with No Spread (SRNS) timing architectures. The IDT5V41315 uses a 25MHz input to generate 4 different output frequencies. The output frequency is selectable via select pins.

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.
