2305B-1DCG

Overview

The Renesas Electronics 2305B-1DCG is a 3.3V zero-delay clock buffer utilizing a Phase-Locked Loop (PLL) architecture. It provides four low-skew CMOS outputs with 25 mA drive capability at TTL levels, supporting frequencies up to 133 MHz. The device features full on-chip PLL feedback and operates within a 3 V to 3.6 V supply range. It is available in an 8-pin SOIC package and supports industrial temperature ranges of -40°C to 85°C or commercial ranges of 0°C to 70°C.

Feature Summary

• Zero delay operation achieved through internal PLL feedback
• Four low skew outputs with high drive capability
• Tri-state mode support for board-level testing

Applications

• High-speed clock distribution systems
• Low jitter clock buffering applications
• Board-level signal integrity testing

Procurement Notes

Verify the specific suffix against official documentation to confirm the exact operating temperature range and package variant. Ensure compatibility with 3.3V logic levels and check for RoHS compliance status as defined by the manufacturer's current specifications before procurement.

Selection Notes

Select this component for applications requiring precise clock synchronization without input-to-output latency. Consider the 25 mA output drive strength for driving multiple loads. Verify that the 8-pin SOIC package fits the design constraints and that the operating voltage aligns with the 3.3V system requirements.

Part Context

This part belongs to the 2305B series of clock buffers from Renesas Electronics. It is designed for high-speed digital systems where clock skew and jitter are critical performance factors. The series includes variants with different drive strengths and temperature ratings.

Replacement Considerations

The IDT2305B-1HDCGI8 is listed as an alias for this component family. Verify pinout and electrical parameters against the datasheet when substituting with other zero-delay buffers.
