VF2510BG

Application Specific Clock/Timing Overview

The Renesas VF2510BG is a 3.3V Phase-Lock Loop (PLL) clock driver designed for synchronous SDRAM applications. It distributes one clock input to ten outputs with low skew and jitter, meeting PC133 registered DIMM specifications. The device operates at frequencies from 20MHz to 200MHz within a 2.97V to 3.63V supply range. It features an internal loop filter, eliminating the need for external RC components. The IC is housed in a 24-pin TSSOP package and supports Spread Spectrum Clocking compatibility.

Application Specific Clock/Timing Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence or replacement by newer series variants. Confirm package marking and datasheet revision against current manufacturer documentation prior to procurement to ensure functional compatibility.

Application Specific Clock/Timing Selection Notes

Select this component when a single-ended clock source requires expansion to ten loads with precise phase alignment. Ensure the design accommodates the 3.3V supply voltage and utilizes the FBIN/FBOUT terminals for proper PLL synchronization. Verify that the operating temperature range of 0°C to 70°C meets system environmental requirements.

Application Specific Clock/Timing Part Context

This device belongs to the ICSVF2510 family of clock drivers originally developed by Integrated Circuit Systems, Inc., now part of Renesas Electronics. It serves as a specialized buffer for memory subsystems requiring strict timing constraints and low jitter performance compared to standard fanout buffers.

Application Specific Clock/Timing Replacement Considerations

Check for direct replacements such as the CDCVF2510 series from Texas Instruments which offers similar PLL-based clock buffering functionality in comparable packages.
