2309-1DCGI8

Overview

The Renesas Electronics Corporation 2309-1DCGI8 is a Zero Delay Buffer IC designed for clock distribution applications. It operates within a supply voltage range of 3V to 3.6V and supports maximum frequencies up to 133MHz. The device features a 1:9 input-to-output ratio, converting a single LVTTL input into nine LVTTL outputs. Packaged in a 16-SOIC (0.154", 3.90mm Width) surface-mount format, it is intended for systems requiring low-skew clock buffering with PLL-based synchronization capabilities.

Feature Summary

• Zero Delay Buffer architecture utilizing PLL feedback from the CLKOUT pad
• 1:9 Input/Output Ratio with LVTTL signal compatibility
• Maximum Operating Frequency of 133MHz at 3.3V
• 16-SOIC Surface Mount Package

Applications

• High-speed digital system clock distribution
• FPGA and ASIC clock buffering
• Telecommunications equipment timing circuits

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence or lifecycle changes. Confirm RoHS compliance status as specifications may vary by manufacturing date. Ensure the 16-SOIC package dimensions match the target PCB footprint before integration.

Selection Notes

Select this component when a single-ended LVTTL source requires expansion into nine synchronized outputs with minimal skew. Verify that the 3V to 3.6V supply voltage aligns with the system power rails. Consider the 133MHz frequency limit against the required clock speed.

Part Context

This part belongs to the IDT/Renesas 2309 series of zero-delay buffers. It shares functional similarities with variants like the 2309-1HDCG but differs in packaging and specific electrical characteristics. The 'I' suffix typically denotes industrial temperature range availability in related family members.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate pin-compatible alternatives such as the NB2309AI1DR2G only after verifying electrical parameter alignment.
