2305A-1DCG8

Overview

The Renesas Electronics Corporation 2305A-1DCG8 is a zero delay buffer integrated circuit designed for clock distribution applications. It operates within a supply voltage range of 3 V to 3.6 V and supports input frequencies from 10 MHz to 133 MHz. The device features one input and five outputs, packaged in an 8-SOIC (DCG8) format with a pitch of 1.27 mm. It provides low skew performance with a maximum output skew of 250 ps and cycle-to-cycle jitter under 200 ps. The component is rated for industrial operating temperatures between -40°C and +85°C.

Feature Summary

• Zero delay buffering using on-chip PLL technology
• Low skew outputs (<250 ps) and low jitter (<200 ps)
• Supports frequencies up to 133 MHz
• Industrial temperature range (-40°C to +85°C)

Applications

• High-speed clock distribution systems
• Data communication equipment requiring precise timing
• Network infrastructure components

Procurement Notes

Verify the specific suffix '8' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the selected variant matches the required industrial temperature rating for the target environment.

Selection Notes

Select this component for designs requiring a single-input, five-output clock buffer with minimal phase noise. Compare against the standard drive version if higher current drive capability is not necessary. Verify that the 8-SOIC package dimensions fit the PCB layout constraints and that the 3.3V nominal supply aligns with system power rails.

Part Context

This part belongs to the IDT 2305A series of zero delay buffers, which are widely used for clock signal conditioning. The 'A' designation typically denotes specific electrical characteristics or revisions within the family. The device replaces older discrete clock buffer solutions by integrating the PLL and feedback network on a single chip.

Replacement Considerations

Direct substitutes include other parts from the 2305A family, such as the 2305A-1DCGI8 for industrial temperature variants in tube packaging. Cross-reference pinouts and electrical specifications carefully when considering alternative manufacturers.
