2305MI-1HLF

Overview

The Renesas 2305MI-1HLF is a zero-delay low-skew clock buffer utilizing a Phase-Locked Loop (PLL) architecture. It operates at 3.3V with an industrial temperature range of -40°C to +85°C. The device provides four low-skew outputs with less than 250 ps skew and device-to-device skew under 700 ps. It supports clock frequencies from 10 MHz to 133 MHz, featuring full CMOS outputs with 25 mA drive capability at TTL levels. The component includes a tri-state mode for board-level testing and offers 5V tolerant CLKIN inputs.

Feature Summary

• Zero input-output delay achieved through on-chip PLL feedback
• Four low-skew outputs ensuring precise signal distribution
• Tri-state mode support for comprehensive board-level testing

Applications

• High-speed digital system clock distribution
• Low-jitter clock buffering in communication equipment
• Industrial control systems requiring precise timing

Procurement Notes

Verify the specific suffix 'LF' indicates lead-free compliance and confirm package type as SOIC-8. Ensure the operating temperature range matches the industrial specification (-40°C to +85°C). Cross-reference the manufacturer part number with official Renesas documentation to confirm current status and availability, as this variant may be obsolete or superseded by newer series members.

Selection Notes

Select this component when zero delay and low skew are critical for system synchronization. It is suitable for applications requiring 3.3V operation with robust drive capabilities. Consider the industrial temperature range if the environment exceeds commercial limits. Verify that the output count and frequency requirements align with the 133 MHz maximum limit.

Part Context

This part belongs to the Renesas 2305 series of zero-delay buffers. It is functionally similar to IDT 2305 variants but manufactured by Renesas Electronics. The 'MI' suffix typically denotes the industrial temperature grade, while 'H' indicates high-drive performance characteristics compared to standard versions.

Replacement Considerations

Public confirmed substitutes include the IDT2305-1DCGI and IDT2305-1HDCGI. These parts share identical pinouts and functional specifications. Verify compatibility with existing PCB layouts and ensure voltage and temperature ranges match the design requirements before substitution.
