2309-1HPGGI8

Overview

The IDT2309-1HPGGI8 is a Zero Delay Buffer manufactured by Renesas Electronics Corporation, designed for high-speed clock distribution. It accepts one LVTTL input and provides nine CMOS/LVTTL outputs with a 1:9 ratio. The device operates at frequencies up to 133MHz using a 3V to 3.6V supply voltage. It features an on-chip PLL for low jitter performance and is housed in a 16-TSSOP package (4.40mm width). This specific suffix variant supports the commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero Delay Buffer architecture aligns output phase with input clock
• 1:9 Input-to-Output ratio with 9 low skew outputs
• Maximum operating frequency of 133MHz
• Single-supply operation at 3V to 3.6V

Applications

• High-speed clock distribution networks
• System synchronization in digital logic circuits
• Jitter reduction in data communication interfaces

Procurement Notes

This component is identified as End-of-Life (EOL) by the manufacturer. Verification of current stock availability through authorized distributors is required before procurement planning. Alternative sourcing strategies or redesign may be necessary due to the discontinued status.

Selection Notes

Select this part when a single-ended LVTTL input must drive nine single-ended loads with minimal skew. Ensure the application requires the commercial temperature range (0°C to 70°C); industrial variants (-40°C to 85°C) are available under different suffixes such as IDC. Verify that the 133MHz maximum frequency meets system timing requirements.

Part Context

The IDT2309 series comprises zero delay buffers based on proprietary low-jitter PLL techniques. The -1H designation indicates a high-drive version with faster rise and fall times compared to standard drive versions. The GGI8 suffix specifically denotes the 16-TSSOP package configuration with tape-and-reel packaging.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material for this specific EOL variant. Users should consult manufacturer documentation for recommended replacements or equivalent family members.
