2309A-1HPGGI

Overview

The Renesas 2309A-1HPGGI is a low phase noise, high-speed PLL-based zero delay buffer designed for clock distribution. Operating at 3.3V, it accepts one reference input and provides nine low-skew outputs with frequencies up to 133 MHz. The device utilizes an on-chip PLL that locks to the input clock via the REF pin, achieving zero delay by aligning output phases with the incoming signal. It features separate output enables for two banks (five and four outputs) and operates within a temperature range of -40°C to 85°C in a 16-pin TSSOP package.

Feature Summary

• Zero delay buffer architecture using proprietary low jitter PLL techniques
• Nine low skew LVTTTL outputs supporting frequencies up to 133 MHz
• Separate output enable control for two distinct output banks
• Low cycle-to-cycle jitter specification of less than 200 ps

Applications

• High-speed clock distribution networks
• System synchronization in data communication equipment
• Clock buffering for high-performance processors and FPGAs

Procurement Notes

Verify the specific suffix 'GGI' corresponds to the 16-TSSOP package with 0.65mm pitch as documented. Confirm the operating temperature range covers industrial requirements (-40°C to 85°C). Ensure compatibility with 3.3V supply voltage levels. Check for any recent Product Change Notifications (PCN) regarding assembly sites or material changes from Renesas Electronics.

Selection Notes

Select this component when a zero-delay phase alignment between input and multiple outputs is required. The 2309A-1H variant offers higher drive strength compared to standard versions, suitable for driving heavier loads. Verify that the 133 MHz maximum frequency meets system timing constraints. Consider the 16-pin TSSOP footprint for PCB layout compatibility.

Part Context

The 2309A series serves as a 16-pin version of the 2305A, providing enhanced output capabilities. It is part of Renesas' portfolio of PLL-based clock drivers designed to replace discrete buffering solutions. The device integrates the feedback loop internally, eliminating the need for external RC networks typically required in older clock buffer designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Renesas Electronics directly for qualified alternatives or cross-reference with IDT-branded equivalents if applicable, ensuring electrical parameters such as skew and jitter remain compatible.
