252M-49LF

Overview

The 252M-49LF is a Versaclock synthesizer manufactured by Renesas Electronics. It functions as a clock generator and jitter cleaner, designed to provide precise timing signals for digital systems. The component operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 140 MHz. It is housed in an 8-pin SOIC package and is rated for industrial temperature operation from -40°C to +85°C. This device is part of the 252PM series, which focuses on low-power clock generation solutions.

Feature Summary

• Versaclock Synthesizer architecture for clock generation and jitter cleaning
• Operates at frequencies up to 140 MHz with low power consumption
• Available in compact 8-pin SOIC surface-mount package
• Industrial temperature range support (-40°C to +85°C)

Applications

• Telecommunications equipment requiring stable clock sources
• Data communication interfaces needing jitter reduction
• Embedded systems utilizing Versaclock family components

Procurement Notes

The 252M-49LF is listed as End-of-Life (EOL) or discontinued by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors or verifying specific stock status through authorized channels. Designers should consider obsolescence management strategies when integrating this component into new products.

Selection Notes

Select the 252M-49LF for applications requiring a dedicated clock synthesizer in an 8-pin SOIC form factor. Ensure the design accommodates the 3.0 V to 3.6 V supply voltage requirement. Verify that the 140 MHz maximum frequency meets system timing needs. Due to its discontinued status, evaluate alternative active parts from the same Versaclock family if long-term supply stability is required.

Part Context

This component belongs to the Renesas Versaclock family, specifically the 252PM series. These devices are engineered to replace crystal oscillators and PLLs with programmable, low-jitter clock solutions. The 252M-49LF variant offers a fixed output configuration suitable for standard interface timing applications.

Replacement Considerations

As the 252M-49LF is discontinued, verify compatible replacements within the Renesas Versaclock portfolio. Check datasheets for pin compatibility and electrical parameter alignment. Consider active alternatives such as other members of the 252PM series or newer Versaclock generations that offer similar packaging and performance characteristics.
