1. 概述：

It is used to generate a stable, high-speed clock from an external slower clock signal. It integrates one Voltage-Controlled Oscillator (VCO), one Phase-Frequency Detector (PFD), one Low-Pass Filter (LPF), one 8-bit programmable divider, and other associated support circuitries. This PLL supports an operating voltage ranging from 0.81 V to 0.99 V with an operating junction temperature ranging between -40 °C and 125 °C. This IP uses the input operating frequency of PFD ranging from 6 MHz to 25 MHz and generates the output frequency ranging from 25 MHz to 1300 MHz. 
 
The jitter performance of a PLL is highly dependent on the floor plan of ASIC. Because PLL is a sensitive cell when integrated into an ASIC design, the best way to maximize its capacity is to keep PLL away from the noisy blocks in the core region, such as the memory block and the high-driving logic circuit, and the I/O region, such as the high-driving I/O. This PLL must be placed around the I/O area. Providing sufficient space between this PLL and the noisy blocks is a simple and effective approach to reduce the coupled substrate noise.
