2305M-1HLF

Overview

The 2305M-1HLF is a 3.3V zero-delay clock buffer manufactured by Renesas Electronics, utilizing proprietary low-jitter Phase-Locked Loop (PLL) technology. It features five CMOS outputs with 25 mA drive capability and operates within a frequency range of 10 MHz to 133 MHz. The device provides four low-skew outputs with skew less than 250 ps and inter-device skew under 700 ps. It supports tri-state mode for board-level testing and accepts 5 V tolerant CLKIN signals. Packaged in an 8-pin SOIC, it is designed for industrial temperature ranges.

Feature Summary

• Zero delay buffer architecture based on proprietary PLL techniques for minimal phase noise
• Five full CMOS outputs providing 25 mA drive capability at TTL levels
• Low skew performance with output skew under 250 ps and device-to-device skew below 700 ps
• Tri-state mode support enabling effective board-level testing capabilities

Applications

• High-speed clock distribution systems requiring low jitter
• Board-level testing environments utilizing tri-state functionality
• Industrial applications operating within specified temperature ranges

Procurement Notes

Verify the specific suffix 'M' against official Renesas documentation to confirm exact electrical characteristics and package dimensions. Ensure the selected variant matches the required industrial temperature range and voltage specifications. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and availability. Confirm RoHS compliance details directly from the latest datasheet before integration.

Selection Notes

Select this component when zero input-output delay is critical for system synchronization. The 25 mA output drive strength suits direct loading of TTL-compatible loads without additional buffering. Consider the 5 V tolerant CLKIN feature if interfacing with higher voltage logic sources. Verify that the 8-pin SOIC package fits the available PCB footprint constraints.

Part Context

This component belongs to the 2305 series of high-speed PLL-based clock buffers originally developed by IDT and now managed by Renesas Electronics. The series addresses high-speed clock distribution needs where low phase noise and precise timing are essential. The 2305M-1HLF represents a specific configuration within this family optimized for 3.3V operation and industrial reliability.

Replacement Considerations

Public confirmed substitute part numbers include 2305-1HDCG and 2305A-1HDCGI8. Verify pinout compatibility and electrical parameter alignment before substitution.
