Core Powered Wide Range Programmable Integer PLL on TSMC CLN3E

Overview

The Core Powered Wide Range PLL is easy to integrate, requiring no analog power supply, and can be placed anywhere on a chip.

This Wide Range PLL addresses a large portfolio of applications, ranging from simple clock de-skew and non-integer clock multiplication to programmable clock synthesis for multi-clock generation. These PLLs are designed for digital logic processes and use robust design techniques to work in noisy SoC environments, such as high speed communication to low power consumer to memory interfaces.

The PLL macro is implemented in Analog Bits’ proprietary architecture that uses core and thick-oxide devices, on a core level power supply.
