The ZL30281 is a high-performance PCIe Gen 1-6 clock generator. From a 25MHz crystal or CMOS input these devices generate 100 MHZ in four pre-programmed output configurations immediately on power-up. The devices have industry-leading output jitter of 160fs RMS (12kHz to 20MHz).

The ZL30291 CK440 clock generator delivers leading-edge, ultra-low jitter and PCIe Gen 6 performance for today and tomorrow’s data center applications. Providing up to 19 ultra-low jitter differential outputs, the CK440 also has a significant margin to meet PCIe Gen 6 requirements used in single-board, rack-optimized, multi-node and modular server designs. Additionally, when combining the ZL30291 CK440 clock generator with the [ZL40292](https://www.microchip.com/en-us/product/zl40292) DB2000 and DB2000Q [ZL40294](https://www.microchip.com/en-us/product/zl40294), you can implement a complete Intel reference timing solution that drives additional peripherals, including Solid-State Drives (SSD), Universal Serial Bus (USB) controllers and Serial Advanced Technology Attachment (SATA) devices. The ZL30291 operates from 3.3V±10% supply to meet PCIe Electromechanical Specification that requires 3.3V supply tolerance of ±9%. Its operation is guaranteed over the industrial temperature range of –40°C to +85°C. Applications include: * PCIe Gen1/2/3/4/5/6 Clock Generation * Platform Tuning * Intel QPI/UPI * Servers * Storage and Data Centers * Switches and Routers
