2305A-1DCGI8

Overview

The Renesas 2305A-1DCGI8 is a zero-delay clock buffer IC designed for high-speed digital systems. It operates on a single 3V to 3.6V supply and supports input frequencies from 10 MHz to 133 MHz. The device features one LVCMOS input and five CMOS/LVCMOS/TTL outputs, providing a 1:5 distribution ratio. Packaged in an 8-SOIC (0.154" width) surface-mount case, it functions within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 0 ps and peak-to-peak jitter of 200 ps.

Feature Summary

• Zero-delay PLL-based architecture ensures minimal input-to-output skew.
• Supports output frequencies up to 133 MHz with low phase noise.
• Industrial temperature rating (-40°C to +85°C) for robust operation.
• Compatible with LVTTL inputs and CMOS/LVCMOS/TTL outputs.

Applications

• High-speed data acquisition systems requiring precise clock synchronization.
• Telecommunications equipment utilizing low-skew clock distribution.
• Industrial control boards needing reliable timing signals across wide temperature ranges.

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) versus commercial variants. Confirm RoHS3 compliance status as per current manufacturer documentation. Ensure the 8-SOIC package dimensions match the target PCB footprint constraints before ordering.

Selection Notes

Select this component when zero-delay buffering is required for 1:5 fan-out applications. It is suitable for designs operating between 3V and 3.6V where low jitter (<200 ps P-P) is critical. Consider the 2305-1 series if commercial temperature range suffices, or the 2305A-1H series if higher drive strength is needed.

Part Context

This part belongs to the IDT 2305 family of zero-delay buffers, now manufactured by Renesas Electronics following the Integrated Device Technology acquisition. The 2305A variant typically denotes specific performance enhancements or updated manufacturing processes within the legacy IDT portfolio.

Replacement Considerations
