9EPRS525AGILFT

Overview

The 9EPRS525AGILFT is a clock synthesizer compliant with the Intel CK505 Yellow Cover specification, designed for embedded systems and desktop chipsets. It operates from an external 14.318MHz crystal and provides multiple differential low-power push-pull outputs. Key electrical parameters include CPU output cycle-cycle jitter of less than 85ps, SRC output jitter under 125ps, and PCI output jitter below 250ps. The device supports spread spectrum modulation from 0 to -0.5% down spread and maintains +/- 100ppm frequency accuracy across all outputs.

Feature Summary

• Compliant with Intel CK505 Yellow Cover specification for single-chip desktop chipset solutions
• Provides 2 CPU differential pairs, 7 SRC differential pairs, and various selectable/output configurations including PCI and USB clocks
• Supports CPU clock frequencies up to 400MHz and PCIe Gen2 when sourced from PLL3
• Features tight ppm accuracy on all outputs for Serial ATA and PCI-Express support

Applications

• Intel desktop chipset implementations
• Embedded systems requiring CK505 derivative timing
• Serial ATA and PCI-Express interface synchronization

Part Context

The 9EPRS525AGILFT belongs to the 9EPRS525 series, which serves as a derivative of the CK505 clock generator. This component is manufactured by Renesas Electronics and is housed in a 56-pin TSSOP package. The 'AGILFT' suffix indicates specific packaging and compliance attributes within this product line.

Replacement Considerations

The 9EPRS525AGILFT is listed as obsolete. Designers should consult Renesas for current alternatives or verify compatibility with existing inventory before finalizing designs.
