4-Phase LC PLL on INTEL 16

Overview

The LCPLL (with 4-phase outputs) addresses stringent performance requirements for various low jitter applications, including high-speed serial link and data converter applications. This PLL is designed for digital logic processes and uses robust design techniques to work in noisy SoC environments.

The PLL macro is implemented in Analog Bits’ proprietary architecture that uses core and 1.8V IO devices. With all components integrated, jitter performance and standby-power are significantly improved.
