95V857AG

Application Specific Clock/Timing Overview

The Renesas 95V857AG is a PLL-based clock buffer and driver designed for DDR memory applications. It operates on a single 2.3V to 2.7V supply and supports frequencies up to 233MHz. The device features a 1:10 differential input-to-output ratio, utilizing SSTL-2 output standards. Packaged in a 48-TFSOP (TSSOP) housing, it integrates a Phase-Locked Loop for low skew and jitter performance. This component functions as a zero-delay buffer, synchronizing inputs directly to outputs to minimize board-level latency in high-speed memory systems.

Application Specific Clock/Timing Feature Summary

• 1:10 Differential Input/Output Ratio

• Integrated PLL for Zero-Delay Buffering
• 2.3V to 2.7V Single Supply Operation

Application Specific Clock/Timing Applications

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

Application Specific Clock/Timing Procurement Notes

The 95V857AG is officially listed as obsolete by the manufacturer. Verification of RoHS compliance indicates non-compliance with current environmental standards. Sourcing requires confirmation of legacy stock availability or authorized distributor surplus channels. Designers should verify package pinout compatibility if substituting from other revisions within the 95V857 family.

Application Specific Clock/Timing Selection Notes

Select this component only for existing designs requiring specific 2.5V SSTL-2 buffering. Verify that the 48-TFSOP footprint matches the PCB layout. Consider the 233MHz maximum frequency limit against system requirements. Due to obsolescence, evaluate alternative clock drivers with modern packaging and compliance certifications for new hardware development.

Application Specific Clock/Timing Part Context

This part belongs to the IDT/Renesas 95V series of wide-range frequency clock drivers. It shares functional similarities with variants like the 95V857C and ICS95V857AG. The device was originally manufactured by Integrated Device Technology before its acquisition by Renesas Electronics Corporation.

Application Specific Clock/Timing Replacement Considerations

Public documentation lists the 95V857CGLF and 95V857CGLFT as related variants within the same product line. These alternatives offer similar electrical characteristics but may differ in lead-free status or packaging format.
