9LPRS511EGLF

Overview

The Renesas 9LPRS511EGLF is a Timing Control Hub™ clock and frequency synthesizer IC designed for Intel CPU and PCI Express (PCIe) applications. It features a single circuit with a 1:22 input-to-output ratio, generating up to 22 differential clock outputs from a crystal input. The device operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 400MHz. Packaged in a 64-TFSOP (64-TSSOP) surface-mount case, it functions within an operating temperature range of 0°C to 70°C.

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct distribution channels. Confirm RoHS3 compliance and MSL level 1 status when sourcing replacements.

Selection Notes

Select this part for designs requiring a high-fanout clock distribution solution specifically optimized for Intel processors and PCIe interfaces. Ensure the design accommodates the 3.135V to 3.465V supply requirement and the 64-pin TSSOP footprint constraints.

Part Context

The 9LPRS511 belongs to the TCH™ family, which integrates multiple clock generation functions into a single chip to reduce board space and complexity in server and workstation platforms. It replaces discrete oscillator and buffer solutions for high-speed bus timing.
