95V857AKLF

Application Specific Clock/Timing Overview

The 95V857AKLF is a PLL-based clock driver manufactured by Renesas Electronics Corporation, designed for memory applications. It features a 1:10 differential input-to-output ratio and operates within a supply voltage range of 2.3V to 2.7V. The device supports maximum frequencies up to 233MHz and utilizes SSTL-2 output signaling. Packaged in a 48-TFSOP (TSSOP) surface-mount housing, it functions as a zero-delay buffer with integrated feedback pins for input-to-output synchronization. The component is rated for an operating temperature range of 0°C to 85°C.

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'AKLF' against official Renesas documentation to confirm package type and RoHS compliance status. Cross-reference with the discontinued 95V857AG variant to ensure pinout compatibility. Confirm current availability status through authorized distributors, as this series may be subject to end-of-life notices or alternative packaging changes.

Application Specific Clock/Timing Selection Notes

Select this component for DDR memory designs requiring low skew and jitter performance. Ensure the system power supply strictly adheres to the 2.3V–2.7V specification. Verify that the PCB layout accommodates the 48-TFSOP package dimensions. Consider the 233MHz maximum frequency limit when designing for high-speed data rates.

Application Specific Clock/Timing Part Context

This part belongs to the 95V Series of PLL-based clock drivers originally developed by IDT and continued under Renesas Electronics. It serves as a specialized solution for distributing reference clocks to multiple memory devices with minimal delay variation. The family is characterized by its ability to synchronize input and output edges via internal feedback loops.

Application Specific Clock/Timing Replacement Considerations

Public sources indicate the 95V857AG and 95V857CGLF are related variants within the same product line. However, specific substitution requires verification of package compatibility and electrical parameter alignment with the original design specifications.
