2305B-1HDCGI

Overview

The Renesas 2305B-1HDCGI is a zero-delay clock buffer featuring an integrated Phase-Locked Loop (PLL). It accepts a single LVCMOS input and provides five LVCMOS outputs, operating within a frequency range of 10 MHz to 133 MHz. The device functions at a core voltage of 3.3 V (range 3 V to 3.6 V) and ensures minimal propagation delay with output skew under 250 ps. Packaged in an 8-pin SOIC, it supports industrial temperatures from -40°C to +85°C.

Feature Summary

• Zero-delay PLL architecture aligns output phase with the input reference clock.
• Five LVCMOS outputs with 25 mA drive capability for TTL levels.
• Low jitter performance with cycle-to-cycle jitter typically under 200 ps.
• Tri-state mode support for board-level testing and power-down capabilities.

Applications

• High-speed clock distribution in embedded systems.
• Synchronization interfaces for microprocessors and memory modules.
• Industrial control equipment requiring low-skew timing signals.

Procurement Notes

Verify the specific suffix 'B' against official Renesas documentation to confirm pinout or electrical characteristics distinct from the standard 2305-1 series. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning.

Selection Notes

Select this component when a single-ended LVCMOS input must be distributed to five loads with strict phase alignment requirements. Ensure the system operates within the 3.3 V supply range and that the 8-pin SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the Renesas 2305 family of high-speed clock buffers. It serves as a specialized variant designed for applications requiring precise clock skew management and low phase noise compared to standard fan-out buffers.

Replacement Considerations

The IDT2305-1HDCGI is a confirmed equivalent part number for this component. Verify functional compatibility before substitution.
