2305B-1HDCGI8

Overview

The Renesas 2305B-1HDCGI8 is a zero-delay clock buffer utilizing a Phase-Locked Loop (PLL) architecture. It operates at a supply voltage of 3.3V with an input frequency range of 10 MHz to 133 MHz. The device features one LVCMOS input and five LVCMOS outputs, providing full CMOS output drive capability at TTL levels. It ensures low phase noise and high-speed performance with four low-skew outputs characterized by less than 250 ps skew. The component supports tri-state mode for board-level testing and is housed in an 8-pin SOIC package.

Feature Summary

• Zero-delay buffering via on-chip PLL feedback
• Low skew output distribution for timing integrity
• Tri-state mode support for system testing
• High drive capability compatible with TTL levels

Applications

• Clock distribution in high-speed digital systems
• Jitter cleaning and phase alignment
• Board-level signal routing for multiple loads

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range of -40°C to 85°C. Confirm the '8' suffix corresponds to the reel packaging format. Ensure compatibility with 3.3V logic families. Cross-reference the manufacturer part number against official Renesas documentation to distinguish from similar variants within the 2305 series. Validate RoHS compliance status prior to integration.

Selection Notes

Select this component when zero input-to-output delay is critical for system synchronization. Choose this buffer for applications requiring up to five fan-out loads from a single source. Consider the 133 MHz maximum frequency limit for high-speed designs. Opt for this device over standard buffers when low skew and jitter reduction are primary design constraints.

Part Context

This part belongs to the 2305 series of clock buffers designed for low phase noise and high-speed operation. It represents a specialized variant within the Renesas portfolio, focusing on precise clock distribution. The series utilizes advanced sub-micron CMOS processes to achieve low power consumption while maintaining robust signal integrity across various industrial and commercial environments.

Replacement Considerations

The IDT2305B-1HDCGI8 is listed as an alias for this component. Verify pinout and electrical specifications before substituting with other members of the 2305 family, such as the 2305-1HDCGI8, to ensure functional equivalence.
