The economics of a system-on-chip ASIC have evolved over the last decade, driven by forces such as cost to yield a transistor, wafer defect density and chip yield, and the drive for greater performance and efficiency. As process nodes continued to shrink from 28nm down to 3nm, we observed Moore’s Law begin to break down, and the cost to yield 100 million transistors normalized to 28nm was either flat or, arguably, increased.
Fractional-N PLLs are a useful class of PLLs and not well understood. This paper explains in simple terms how these differ from a regular integer PLL. Common applications are listed along with a brief description of the key performance parameter – jitter.
Like most types of circuits, there is no such thing as a "one size fits all" PLL. This article will explore the trade-offs in PLL performance and design and look for a solution to most SOC PLL needs.
In this paper, we present a flexible ring oscillator IP designed for a 40nm CMOS technology, whose oscillation frequency can be chosen from 200kHz to 20MHz. It was developed using a new design approach, in which analog IPs are designed from scratch to be flexible, employing modular blocks that can be easily customized. The IP is silicon proven. It works with a supply voltage of 1.2V and features 5% frequency accuracy, occupying an area of 0.0022mm2.
This article reviews the functional-safety attributes of Classical CAN and CAN FD, then explains how CAN XL preserves and extends them. It also discusses higher-layer safety protocols, fault-tolerant CAN XL controller implementations, and CANsec, the CAN XL security extension inspired by the MACsec model. Finally, it highlights how the CAST CAN XL controller IP and CANsec acceleration IP can support the efficient deployment of safety- and security-capable in-vehicle networks.
This article outlines Key ASIC R&D team's upcoming PLL suitable for high-speed SerDes having ultra low jitter with LC- tank VCO, and supporting up to 16 GHz output clock to sample the data.
