2308-5HPGGI

Overview

The Renesas Electronics Corporation 2308-5HPGGI is a discontinued 3.3V Zero Delay Clock Multiplier belonging to the IDT 2308 family. It utilizes a Phase-Lock Loop (PLL) architecture to distribute one clock input to two banks of four outputs, providing eight total LVCMOS outputs. The device supports multiplication factors of 2x and 4x, operating within an input frequency range of 10MHz to 133MHz. Key electrical parameters include output skew less than 200 ps and cycle-to-cycle jitter below 200 ps. It operates on a single 3.3V VDD supply without requiring an external RC network.

Feature Summary

• Zero delay PLL operation synchronizes output phase with the input clock reference.
• Provides 2x and 4x multiplication options for frequencies between 10MHz and 133MHz.
• Features high-drive capability in a TSSOP-16 package.
• Includes separate output enable controls for each of the two output banks.

Applications

• High-speed clock distribution systems requiring zero delay alignment.
• Multiplication of reference clocks for digital logic interfaces.
• System testing modes utilizing direct input clock drive capabilities.

Procurement Notes

The 2308-5HPGGI is listed as obsolete or end-of-life by the manufacturer. Availability is restricted to remaining stock from distributors. Verification of authenticity and storage history is critical due to the component's discontinued status. Buyers should confirm the specific suffix details match the required high-drive specifications before procurement.

Selection Notes

Select this component when a 3.3V zero-delay multiplier with 2x or 4x output ratios is required. Ensure the application frequency falls within the 10MHz to 133MHz range. The TSSOP-16 package must be compatible with the PCB footprint. Note that this variant provides high-drive outputs; if standard drive is sufficient, other family members may be considered, though availability remains limited across the series.

Part Context

This part belongs to the IDT 2308 series of clock multipliers, which were later integrated into Renesas Electronics following acquisitions. The '5H' designation typically indicates a specific configuration within the family offering 2x and 4x multiplication with high-drive output buffers. The 'GGI' suffix denotes the TSSOP-16 package type and lead-free composition.

Replacement Considerations

As the component is obsolete, direct replacements are scarce. Engineers may need to evaluate newer clock generator families from Renesas or other manufacturers that support similar voltage levels and frequency ranges. Functional compatibility requires verifying pinout correspondence and electrical characteristics such as jitter and skew performance.
