IDT2308-1HPGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308-1HPGI is a 3.3V zero-delay buffer (ZDB) clock multiplier manufactured by Integrated Device Technology, now part of Renesas Electronics Corporation. It operates within the commercial temperature range of 0°C to +70°C and utilizes a 16-pin TSSOP package. The device functions as a high-speed phase-lock loop (PLL) clock multiplier designed for applications ranging from 10MHz to 133MHz. It features one reference clock input and distributes the signal to two banks of four outputs each. Key electrical characteristics include an output skew of less than 200 ps and cycle-to-cycle jitter under 200 ps. The supply voltage ranges from 3.0V to 3.6V.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero-delay PLL architecture synchronizes output clocks to the input reference with minimal delay.
• Distributes one clock input to eight outputs organized into two independent banks of four.
• Supports operating frequencies from 10MHz up to 133MHz with low cycle-to-cycle jitter (<200 ps).
• Features separate output enable controls for each bank via S1 and S2 select inputs.

Clock Generators, PLLs, Frequency Synthesizers Applications

• SDRAM memory systems
• Telecommunications equipment
• Datacom infrastructure
• PC motherboards and workstations

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the component matches the specific commercial temperature grade (0°C to +70°C), as industrial variants (-40°C to +85°C) exist with different suffixes. Confirm the package type is TSSOP-16 and ensure the ordering suffix aligns with the required shipping packaging format, such as tubes or tape and reel, based on the manufacturer's official ordering guide.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when a standard drive capability is sufficient for the load requirements, as opposed to the -1H, -2H, or -5H high-drive versions. Ensure the application frequency falls between 10MHz and 133MHz. Verify that the system can accommodate the external feedback loop configuration required to close the PLL and achieve zero delay synchronization.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the IDT2308 family of zero-delay buffers. The '1' designation indicates a 1x multiplication factor where both output banks operate at the reference frequency. The 'PGG' suffix specifies the 16-pin TSSOP package in tube form, while the 'I' suffix denotes the commercial temperature rating. High-drive variants are available for heavier loads.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include IDT2308-1DCGI (SOIC package, Industrial temp) or IDT2308-1HPGGI (TSSOP package, Industrial temp). Cross-vendor substitutes require matching the 3.3V ZDB architecture, 16-pin TSSOP footprint, and similar jitter specifications.
