2305MI-1LFT

Overview

The Renesas 2305MI-1LFT is a 3.3V zero-delay low-skew clock buffer utilizing a proprietary PLL for high-speed distribution. It provides four outputs with skew less than 250 ps and device-to-device skew under 700 ps. The component supports clock frequencies from 10 to 133 MHz, featuring full CMOS outputs with 25 mA drive capability at TTL levels. It includes a 5 V tolerant CLKIN input and tri-state mode for board-level testing. Packaged in an 8-pin SOIC, it operates within the industrial temperature range of -40°C to 85°C.

Feature Summary

• Zero delay buffer architecture using on-chip PLL feedback for minimal phase noise
• Four low skew outputs ensuring precise timing alignment across loads
• Tri-state mode support facilitating board-level diagnostic testing
• 5 V tolerant input interface compatible with various logic levels

Applications

• High-speed clock distribution networks
• System-on-module timing synchronization
• Board-level clock buffering for multi-load environments

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required operational range and pin configuration. Cross-reference the manufacturer's current lifecycle status to confirm availability and long-term supply stability before finalizing procurement plans.

Selection Notes

Select this component when zero-input-output delay and sub-nanosecond skew are critical for system timing integrity. It is suitable for applications requiring robust clock distribution up to 133 MHz with strong output drive capabilities. Consider the 8-pin SOIC form factor for space-constrained designs needing reliable PLL-based jitter reduction.

Part Context

This component belongs to the Renesas 2305 series of zero-delay buffers. It is designed to replace older discrete clocking solutions by integrating PLL functionality into a single IC. The series addresses high-speed clock distribution challenges by providing deterministic latency and low jitter performance essential for modern digital systems.

Replacement Considerations

The 2305MI-1HLFT serves as a high-drive variant within the same family, offering faster rise and fall times while maintaining zero-delay functionality. Verify pin compatibility and electrical specifications when substituting between standard and high-drive versions.
