95V857AGLN

Application Specific Clock/Timing Overview

The Renesas 95V857AGLN is a PLL-based clock driver designed for DDR memory applications. It functions as a zero-delay buffer with a 1:10 input-to-output ratio, distributing differential SSTL_2 clock signals. The device operates within a supply voltage range of 2.3V to 2.7V and supports maximum frequencies up to 233MHz. Packaged in a 48-TFSOP (TSSOP) surface-mount enclosure, it is rated for operation between 0°C and 85°C. This component provides low skew and low jitter performance suitable for high-speed memory synchronization.

Application Specific Clock/Timing Feature Summary

• Zero-delay buffer architecture for DDR memory synchronization
• 1:10 differential clock distribution ratio with SSTL_2 outputs
• Operates at frequencies up to 233MHz with 2.3V-2.7V supply
• Integrated PLL for low skew and low jitter performance

Application Specific Clock/Timing Applications

• DDR Memory Modules
• Zero Delay Board Fan Out
• Registered DIMM Solutions

Application Specific Clock/Timing Procurement Notes

Verify the exact suffix 'LN' against official Renesas documentation, as standard listings typically use 'AG' or 'AGLF'. Confirm RoHS compliance status, as earlier variants like the AG were non-compliant. Check current lifecycle status, as many devices in this series are marked obsolete or not recommended for new designs.

Application Specific Clock/Timing Selection Notes

Select this component when designing DDR memory interfaces requiring precise clock alignment. Ensure the design supports the required 2.3V to 2.7V power domain. Verify that the 48-TFSOP package fits the PCB layout constraints and that the thermal requirements for the 0°C to 85°C operating range are met.

Application Specific Clock/Timing Part Context

This part belongs to the 95V857 family of wide-range frequency clock drivers originally developed by Integrated Device Technology (IDT) and later acquired by Renesas. These devices are engineered to provide complete DDR registered DIMM solutions, often used in conjunction with other specific memory interface controllers.

Application Specific Clock/Timing Replacement Considerations

Publicly confirmed substitute part numbers for the specific 95V857AGLN variant are not available in the provided data. Consider checking for the 95V857CGLF or similar family members, but verify pinout and electrical compatibility directly with manufacturer datasheets before substitution.
