9P935AFLFT

Overview

The Renesas 9P935AFLFT is a DDR I/DDR II Phase Lock Loop Zero Delay Buffer designed for memory applications. It operates within a supply voltage range of 1.7V to 1.9V and supports a maximum frequency of 600MHz. The device features one circuit with a 1:6 input-to-output ratio, providing differential clock inputs and outputs. Packaged in a 28-SSOP case measuring 5.30mm in width, it functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Zero delay buffer architecture with integrated PLL for DDR I/DDR II synchronization
• Supports frequencies up to 600MHz with 1:6 output ratio
• Differential input and output signaling capabilities
• Operates on a 1.7V to 1.9V power supply

Applications

• DDR memory systems
• DDR2 memory architectures
• High-speed digital timing circuits

Procurement Notes

This component is classified as obsolete by the manufacturer. Verification of availability requires checking distributor stock levels or secondary market sources. Compliance with RoHS3 standards is confirmed. Users should review Product Change Notices (PCN) regarding manufacturing discontinuance dated May 2019 before procurement planning.

Selection Notes

Select this part for designs requiring low skew and low jitter clock distribution for DDR memory interfaces. Ensure the design accommodates the specific 1.7V to 1.9V supply voltage requirement. The 28-SSOP package necessitates surface mount assembly techniques compatible with the specified footprint dimensions.

Part Context

The 9P935AFLFT belongs to the 9P935 series of zero delay buffers from Renesas Electronics. It serves as a specialized timing solution for synchronizing clock signals in memory subsystems, replacing earlier discrete timing components with an integrated PLL-based approach for improved performance.

Replacement Considerations

As the 9P935AFLFT is obsolete, verify if the 9P935AGLF (TSSOP-28 package) or other family members are available. Cross-reference pinouts and electrical specifications carefully when evaluating alternative suppliers or updated component revisions.
