2305M-1LF

Overview

The Renesas 2305M-1LF is a high-speed, low-phase noise clock buffer utilizing a proprietary Phase-Locked Loop (PLL) architecture. It functions as a zero-delay fanout buffer designed for precise clock distribution in high-speed applications. The device operates on a single 3V to 3.6V power supply and features LVCMOS output types. It supports a maximum output frequency of 133 MHz with a maximum propagation delay of 0 ps. The component is housed in an 8-SOIC package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Zero-delay PLL architecture ensures minimal skew between input and output clocks
• Low phase noise characteristics for high-speed signal integrity
• Single voltage operation compatible with standard logic levels

Applications

• High-speed clock distribution networks
• System synchronization circuits
• Data converter clocking interfaces

Procurement Notes

Verify the specific suffix 'M' against current Renesas product status, as variants may indicate obsolete or lifecycle-end-of-life status. Confirm RoHS compliance details via official datasheets. Ensure the SOIC-8 package dimensions match PCB footprint requirements. Cross-reference pinouts with the latest manufacturer documentation to avoid interface mismatches during integration.

Selection Notes

Select this component when zero-delay buffering is required for frequencies up to 133 MHz. It is suitable for systems needing low skew without external timing components. Consider the 8-SOIC package for surface-mount assembly. Evaluate power consumption at 35 mA operating current against system thermal constraints. Compare against other members of the 2305 family if different output counts or voltage levels are needed.

Part Context

This part belongs to the Renesas 2305 series of clock buffers. These devices are derived from IDT's legacy PLL technologies. The series focuses on providing clean, jitter-cleaned clock signals for digital systems. The 2305M variant specifically denotes the 133 MHz performance tier in the SOIC-8 package.

Replacement Considerations

Public confirmed substitutes include the IDT2305-1HDCGI8. Verify electrical compatibility and pinout alignment before substitution.
