Recommended Application:

Features/Benefits:

CK505 version 1.1 clock, with fully integrated voltage regulators

and series resistors

•

Supports spread spectrum modulation, 0 to -0.5%

down spread for CPU and SRC clocks

•

Uses external 14.318MHz crystal, external crystal load

caps are required for frequency tuning

•

Available in commercial (0 to +70°C) and industrial

(-40 to +85°C) temperature ranges

•

Meets PCIe Gen2 specifications

Pin Configuration
