95V857AGILF

Application Specific Clock/Timing Overview

The Renesas 95V857AGILF is a DDR clock buffer and driver featuring zero-delay buffering technology. It operates with a single input to ten differential outputs, supporting maximum frequencies up to 233MHz. The device utilizes an internal Phase-Locked Loop (PLL) for jitter attenuation and is designed for memory applications requiring precise timing. It functions within a supply voltage range of 2.3V to 2.7V and is housed in a 48-TFSOP package. The component supports SSTL-2 output standards and operates across a temperature range of 0°C to 85°C.

Application Specific Clock/Timing Feature Summary

• Zero-delay buffering architecture for minimal skew
• 1:10 input-to-output ratio with differential signaling
• Internal PLL for clock jitter reduction
• SSTL-2 compatible outputs for DDR memory interfaces

Application Specific Clock/Timing Applications

• DDR SDRAM clock distribution
• Memory subsystem timing synchronization
• High-speed digital data acquisition systems

Application Specific Clock/Timing Procurement Notes

Verify RoHS compliance status as the base model 95V857AG is listed as non-compliant. Confirm current availability since related variants are marked obsolete. Ensure the suffix 'ILF' corresponds to lead-free specifications if required by assembly processes. Check datasheet revisions for any pinout or electrical parameter changes prior to procurement.

Application Specific Clock/Timing Selection Notes

Select this component when designing DDR memory circuits requiring low-skew clock distribution. Ensure the system power supply remains within the 2.3V to 2.7V range. Verify that the PCB layout accommodates the 48-TFSOP package dimensions. Consider thermal management requirements for operation at the upper limit of the 0°C to 85°C industrial temperature range.

Application Specific Clock/Timing Part Context

This part belongs to the 95V857 family of clock buffers. Variants such as 95V857CGLF and 95V857CKLF exist with different packaging options like TSSOP or VFQFPN. The manufacturer has issued Product Change Notices regarding labeling and packing methods for these devices. Some family members are marked as obsolete, indicating potential lifecycle constraints for long-term production.

Application Specific Clock/Timing Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineering teams should consult official Renesas resources for qualified alternatives or cross-reference with similar zero-delay buffer families if redesign is necessary.
