PCIe® 7.0 Clock Generator from Diodes Incorporated Delivers Sub-30fs Jitter for Next-Gen AI Infrastructure

Key Terms

pcie 7.0 specification technical

PCIe 7.0 specification is the next-generation technical standard that defines how fast and efficiently computer chips and add‑on devices (like graphics cards, storage drives, and network cards) talk to each other inside servers and PCs. Investors should care because it raises the “speed limit” and capacity for data flow—like turning a two-lane road into a much wider, smoother highway—enabling faster products, new use cases, and potential demand and cost changes across chipmakers, hardware vendors and data‑center operators.

rms jitter technical

RMS jitter is a single-number measure of how much the timing of a repeating electronic signal wanders, calculated as the root-mean-square (average size) of those timing deviations. Think of it as how steady a metronome stays: lower RMS jitter means more precise timing, which affects a device’s speed, reliability and ability to meet industry standards. Investors care because high or uncontrolled jitter can reduce product performance, increase defect rates, and affect competitiveness and regulatory approval.

femtoseconds technical

A femtosecond is a unit of time equal to one quadrillionth of a second (10^-15 seconds). It measures ultrafast events such as how quickly electrons move or how light interacts with materials; for investors, femtosecond-scale performance can be a technical advantage in fields like photonics, advanced semiconductors, and scientific instruments, affecting product capabilities and competitive edge. To imagine the scale: a femtosecond compared to a second is like a second compared to about 31.7 million years.

gt/s technical

GT/s stands for gigatransfers per second, a measure of how many billion data transfers a digital link or chip can perform each second. Think of it like counting how many cars can pass a toll booth per second: higher GT/s means more information moves through a connection faster. For investors, GT/s signals the raw throughput and competitive performance of hardware products such as processors, memory interfaces, or interconnects, which can affect product appeal and market value.

current-steering logic technical

Current-steering logic is the electronic control that directs how electrical current is distributed among multiple output channels or electrodes to shape where, how much, and when stimulation or power is delivered. Think of it like a lighting dimmer board that routes brightness to specific bulbs to create a pattern; for medical or electronic devices this affects precision, safety, battery life, and overall performance. Investors care because better current steering can improve product effectiveness, differentiate a device in the market, reduce regulatory risk, and extend battery-powered runtime, all of which can influence commercial success.

SANTA CLARA, Calif.--(BUSINESS WIRE)-- Diodes Incorporated (Diodes) (Nasdaq: DIOD) introduces the PI6CG33A06, a six-output, ultra-low jitter clock generator designed to meet the demands of PCI Express^® (PCIe^®) 7.0 specification while maintaining compliance with all previous generations of the PCIe specification. Announced at PCI-SIG^® Developers Conference, the device is targeted for servers, networking equipment, high-performance computing (HPC) systems, and data center platforms that underpin next-generation AI infrastructure.

The PI6CG33A06 generates precise 25MHz and 100MHz reference clocks and achieves an RMS jitter of less than 30 femtoseconds (fs). This is well below the PCIe 7.0 specification maximum requirement of 67fs and represents a significant improvement over the 80fs level defined by the CK440Q specification from Intel^®. This ultra-low jitter provides greater design margins, helping engineers manage signal integrity challenges across complex PCB traces and connectors.

The device provides a stable reference clock for 128.0 GT/s PCIe links, meeting the bandwidth demands of 800G and 1.6T networking and advanced AI accelerators. Accurate timing at these speeds is critical to maintaining performance and reliability in data center systems.

The PI6CG33A06 implements Diodes’ proprietary low-power, high-speed current-steering logic (LP-HCSL) technology with integrated termination. This reduces clock-related power consumption by at least 50% compared to traditional HCSL solutions and lowers the thermal footprint in high-density AI server racks. The high level of integration eliminates the need for up to 24 external resistors, reducing BOM cost, simplifying PCB layout, and freeing board space for cooling or additional compute and memory resources.

Each of the six outputs includes an individual output enable (OE) pin, allowing designers to manage power more effectively and control system operation with greater flexibility. The device supports Intel CK440Q-Lite specifications and is designed for use in existing server clock architectures. This enables designers to reuse proven system designs while improving timing performance and overall system margin.

“PCIe 7.0 specification is pushing system performance to new heights, particularly for AI and high-bandwidth data center applications,” said Al Yanes, PCI-SIG President and Chairperson. “PCIe clock generators, including Diodes’ PCIe 7.0 clock generator, help streamline system integration to support these advances.”

The PI6CG33A06 is available in a 40-pin, 5mm x 5mm VQFN (ZLF) package, and is priced from $2.80 in 3,000-piece quantities.
