Overview

DLL-based frequency multiplier is a simple to configure and operate block, combining, small area and low current consumption. Block wakes up in “pass-through” mode with redirecting input reference frequency to the output. After being configured and enabled the block waits until DLL locks and then switches output clock signal CLK_OUT to higher frequency. Disabling block switches it back to “pass-through” mode. Any mode switching is glitch-protected.

Arasan’s xSPI/eMMC5.1 PHY: Unified Dual-Mode Physical Layer IP

As SoCs evolve to support a growing range of memory interfaces, designers are faced with the challenge of balancing integration complexity, pin efficiency, and performance scalability. Traditionally, implementing both xSPI (JESD251) for boot and eMMC 5.1 for high-speed storage required separate PHYs, leading to increased silicon area, power consumption, and I/O overhead.

Maximizing Performance & Reliability for Flash Applications with Synopsys xSPI Solution

Systems using SoCs designed in advanced processes generally rely on external Flash devices that use NOR/NAND Flash memory technology for non-volatile storage. NOR Flash memory offers many benefits for device manufacturers and consumers, such as faster reading, low power consumption, and smaller area. In contrast, NAND Flash memories are ideal for applications such as data storage, where higher memory capacity and faster write and erase operations are required.

The common silicon issues in analog IP integration

Despite the fears of the last decade that Moore’s Law had finally reached its end, the microelectronics sector has continued to adapt to new physical constraints and product requirements through sustained innovation and creativity. A major portion of that creative energy has gone into the development of analog, RF and mixed-signal blocks as embeddable IP.
