9EPRS525AGLF

Overview

The Renesas 9EPRS525AGLF is a clock frequency synthesizer IC designed for Intel desktop chipset applications, compliant with the CK505 Yellow Cover specification. It operates on a single supply voltage of 3.135V to 3.465V and supports a maximum output frequency of 400MHz. The device utilizes an external 14.318MHz crystal input and provides 19 outputs with a 1:19 input-to-output ratio. Packaged in a 56-TSSOP (TFSOP) surface-mount housing, it functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Compliant with Intel CK505 Yellow Cover specification for embedded systems
• Provides differential low-power push-pull pairs for CPU and SRC signals
• Supports spread spectrum modulation from 0% to -0.5% down-spread
• Delivers cycle-cycle jitter performance of <85ps for CPU outputs

Applications

• Intel desktop chipset clock generation
• PCI Express Gen2 support via PLL3 sourcing
• Serial ATA tight ppm accuracy timing
• USB 48MHz clock generation

Part Context

The 9EPRS525AGLF belongs to the 9EPRS525 family, which serves as a derivative of the CK505 clock generator. This series is specifically engineered to replace legacy discrete clock solutions in Intel-based desktop platforms, consolidating multiple clock domains into a single integrated circuit.

Replacement Considerations

The 9EPRS525AGLF is listed as obsolete. Designers should verify compatibility with successor models or alternative clock synthesizers that meet the same CK505 specifications and pinout requirements.
