2309-1HPGGI

Overview

The Renesas Electronics Corporation 2309-1HPGGI is a low phase noise, high-speed PLL-based zero delay buffer operating at 3.3V. It provides nine low skew outputs with speeds up to 133 MHz. The device utilizes proprietary low jitter PLL techniques to align input and output clock phases, achieving zero delay. It features full CMOS outputs with 12 mA drive capability at TTL levels and includes tri-state mode for board-level testing. The component is packaged in a 16-pin TSSOP (5.0 x 4.4 x 1.0 mm) with a 0.65 mm pitch.

Feature Summary

• Zero delay buffer architecture using on-chip PLL feedback from CLKOUT pad
• Nine low skew outputs (<250 ps) with 1:9 distribution ratio
• High drive version (-1H) with faster rise/fall times and 12 mA output drive
• Operating frequency range up to 133 MHz at 3.3 V supply voltage

Applications

• High-speed clock distribution systems
• Board-level testing requiring tri-state control
• Low jitter clock generation networks

Procurement Notes

Verify the specific suffix 'HPGGI' against the manufacturer's current datasheet to confirm package type (TSSOP), temperature range (Industrial -40°C to 85°C), and lead-free status. Ensure compatibility with existing PCB footprints for 16-pin TSSOP packages before procurement.

Selection Notes

Select this variant for applications requiring high drive strength and low skew across nine outputs. Compare against the standard 2309-1 model if lower power consumption is prioritized over drive capability. Confirm that the 3.3V LVTTL output levels match the receiving logic inputs.

Part Context

This part belongs to the IDT/Renesas 2309 series of zero delay buffers. It is functionally related to the 2309A series but differs in specific electrical characteristics and packaging options. The -1H designation indicates a high-drive version compared to the base -1 part.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility with other 16-pin zero delay buffers only after consulting the official replacement guide.
