9LP525BF-2LF

Overview

The Renesas 9LP525BF-2LF is a single-circuit clock generator designed for Intel CPU and server applications. It operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 100MHz. The device features a 1:19 input-to-output ratio with crystal input and clock output. It provides differential outputs while maintaining a non-differential input configuration. Packaged in a 56-BSSOP case, it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Single-circuit PLL-based clock generator compliant with Intel CK505 specifications
• Supports up to 19 differential clock outputs from a single crystal input
• Integrated termination resistors for LVPECL outputs reduce external component count
• Operates on a 3.135V to 3.465V supply with 0°C to 70°C industrial temperature range

Applications

• Intel CPU main clock generation
• Server system timing
• High-performance embedded computing platforms

Procurement Notes

Verify the specific suffix 'BF-2LF' against official Renesas documentation to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with existing board layouts requiring 56-pin SSOP footprints. Confirm lead-free status and RoHS compliance through current manufacturer declarations before procurement.

Selection Notes

Select this component when designing systems requiring multiple synchronized differential clocks derived from a single reference source. It is suitable for architectures needing low-jitter performance for high-speed processors. Verify that the 100MHz maximum frequency meets the target bus speed requirements and that the 56-pin package fits the available PCB space.

Part Context

This part belongs to the 9LP series of clock generators, which are derivatives of the legacy CK505 specification. These devices are engineered to provide comprehensive clocking solutions for complex chipset designs, replacing discrete oscillator and buffer combinations with a single integrated circuit.

Replacement Considerations

Check for direct pin-compatible upgrades within the 9LP family or newer generations such as the 9LPRS series. Ensure any substitute maintains the same 56-pin SSOP footprint and electrical characteristics to avoid redesigning the host motherboard.
