CY27410 - 4 PLL Clock that supports 700 MHz, 12 outputs and RMS Jitter of 1 ps. It has Frequency Select, VCXO, ZDB/NZDB and Phase Synchronization. It supports PCIe 1/2/3, 10 GbE and SATA 2.0
FleXO’s Frequency Margining feature easily allows Frequency Margin testing during design, component qualification, and production testing without requiring extra BOM components.
Cypress's application-specific clocks are optimized for the special requirements of their target system applications. They include Direct Rambus® clock generator and PCI Express clock generator.
These are built in dual modulus pre-scaler, adaptable from 50MHz to 3GHz and it can make up low noise small serial input Phase Locked Loop (PLL) frequency enabling pulse swallowing operation.
