Cypress’s latest-generation high-performance clock generator device – CY27410 - is a 4-PLL, 12-output PCIe 3.0- compliant device that provides a host of value-added features. This application note describes how to configure the device in both clock generator and buffer modes with details on input/output standards, external design considerations, reference selection including crystal, and the internal memory structure.

Overview

CY27410 is a 4-PLL spread-spectrum clock generator targeted at consumer, industrial, and networking applications. CY27410 has two inputs and twelve outputs, frequencies up to 700 MHz with a low RMS phase jitter of 1 ps max. CY27410 supports value-added features such as voltage-controlled crystal oscillator (VCXO), frequency select, and zero/nonzero delay buffer (ZDB/NZDB) modes. The part is designed to support reference clocks for key interface standards such as PCI Express (PCIe) 1.0/2.0/3.0, USB 2.0/3.0 and 10-Gigabit Ethernet (GbE).
