2308B-1HPGG8

Overview

The Renesas Electronics Corporation 2308B-1HPGG8 is a 3.3V zero-delay clock multiplier featuring a phase-lock loop (PLL) for high-speed clock distribution and multiplication. It operates within an input frequency range of 10 MHz to 133 MHz, providing a maximum output frequency of 133 MHz. The device utilizes a TSSOP-16 package with a pitch of 0.65 mm and dimensions of 5.0 x 4.4 x 1.0 mm. Key electrical specifications include a cycle-to-cycle jitter of less than 200 ps peak-to-peak and an output skew of 250 ps. It supports LVTTL/LVCMOS outputs and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero-delay buffer architecture aligns output phase with the incoming clock input
• Supports 1x, 2x, and 4x prescaling options via address pins
• Two independent banks of four outputs with separate enable controls
• Low jitter performance with cycle-to-cycle jitter under 200 ps

Applications

• High-speed clock distribution networks
• System synchronization in data communication equipment
• Multiplication of reference clocks for digital logic circuits

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Cross-reference datasheet revisions to ensure compatibility with current design requirements.

Selection Notes

Select the 2308B-1HPGG8 variant specifically for 1x multiplication ratios. Ensure the application requires the TSSOP-16 package format. Verify that the system voltage matches the 3.3V operating requirement and that the thermal environment stays within the 0°C to 70°C commercial range.

Part Context

This component belongs to the IDT 2308B series of PLL clock multipliers. It is designed to replace older discrete clock generation solutions by integrating the feedback loop externally while maintaining zero delay characteristics. The '1H' suffix typically denotes specific drive strength or pinout variations within the broader 2308 family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate newer Renesas clock generator families for functional equivalence if this specific obsolete part is required.
