2309A-1HPGGI8

Overview

The Renesas Electronics Corporation 2309A-1HPGGI8 is a high-speed, low-phase-noise Zero Delay Buffer IC designed for clock distribution applications. It utilizes an internal Phase-Locked Loop (PLL) to align the phase of incoming and outgoing clocks, achieving zero input-to-output delay. The device accepts a single reference input and provides nine low-skew outputs operating at frequencies up to 133 MHz with a 3.3V supply voltage. The -1H suffix indicates a high-drive version featuring faster rise and fall times compared to standard variants. It is housed in a 16-pin TSSOP package with a pitch of 0.65 mm.

Feature Summary

• Zero Delay Buffer architecture using on-chip PLL feedback from CLKOUT pad
• Nine low-skew outputs (<250 ps skew) with high drive capability (-1H version)
• Operates at frequencies from 10 MHz to 133 MHz at 3.3V VDD
• Low cycle-to-cycle jitter (<200 ps) and full CMOS/LVTTL output levels

Applications

• High-speed clock distribution in networking equipment
• Clock buffering for FPGAs and ASICs requiring low skew
• System synchronization in industrial control systems
• Test mode direct input driving for board-level verification

Procurement Notes

Verify component status as the 2309A series may be subject to End-of-Life (EOL) notices or production changes. Check specific datasheets for the -1HPGGI8 variant regarding moisture sensitivity level (MSL 3) and RoHS compliance. Confirm availability through authorized distributors as stock levels fluctuate. Ensure proper handling for surface-mount assembly given the TSSOP package dimensions.

Selection Notes

Select the 2309A-1HPGGI8 when nine buffered outputs are required with minimal skew and zero delay relative to the input. The -1H designation is critical for applications needing higher drive strength and faster edge rates. Compare against the standard 2309A-1 if lower power consumption is prioritized over drive current. Ensure the 3.3V supply voltage matches system requirements and that the 133 MHz maximum frequency covers the target clock speed.

Part Context

This component belongs to the IDT/Renesas 2309 family of Zero Delay Buffers. It is functionally similar to the 2309A-1 but offers enhanced drive characteristics due to the 'H' suffix. The family is designed to replace discrete buffer solutions, reducing board space and improving signal integrity in high-speed digital designs by eliminating external RC networks for PLL configuration.

Replacement Considerations

Public confirmed substitute part numbers were not identified in the provided source material. Verify compatibility with alternative Zero Delay Buffers such as the 2309A-1D or other 1:9 fanout buffers only after confirming pin-out and electrical parameter equivalence.
