2309-1HPGG8

Overview

The IDT2309-1HPGG8 is a zero-delay buffer integrated circuit manufactured by Renesas Electronics Corporation. It features a single LVCMOS input and nine LVCMOS outputs, providing a 1:9 distribution ratio. The device operates at frequencies up to 133 MHz with a supply voltage range of 3V to 3.6V. Packaged in a 16-TSSOP (0.173", 4.40mm Width) surface-mount housing, it is designed for low-skew clock distribution applications within the commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero-delay buffer architecture utilizing an on-chip PLL to align output phase with the input reference clock.
• High-drive capability (-H suffix) ensuring faster rise and fall times compared to standard drive versions.
• Distributes one input clock signal to nine distinct output channels simultaneously.

Applications

• High-speed clock distribution networks requiring precise phase alignment.
• System synchronization in digital logic circuits operating at frequencies up to 133 MHz.
• Low-skew clock buffering for high-performance embedded systems.

Procurement Notes

This component is identified as a discontinued product. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer allocation. Confirm RoHS compliance status, as specific suffixes may indicate lead-free or non-compliant variants depending on the manufacturing date code.

Selection Notes

Select this part when a 1:9 fan-out with zero-delay characteristics is required in a TSSOP package. Ensure the design supports the 3V to 3.6V supply range. Verify that the -H high-drive specification meets the load requirements; if lower power consumption is critical, consider the standard drive variant without the 'H' suffix.

Part Context

The 2309-1 series belongs to the IDT 2309 family of low-phase-noise, high-speed PLL-based buffers. The -1HPGG8 designation specifically denotes the high-drive version packaged in a tape-and-reel format within a 16-pin TSSOP enclosure. This family addresses timing skew issues in complex digital systems by locking output edges to the input reference.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative sourcing requires careful evaluation of pin compatibility and electrical parameter matching against current inventory.
