19 Low-Power Push-Pull HCSL PCIe Outputs
• Seven Dedicated 100 MHz Outputs
• Three Dedicated 25 MHz Outputs
• Nine Selectable Outputs: 25 MHz or 100 MHz

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 DB2000 and DB2000Q 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
