2308A-1HPGGI8

Overview

The Renesas Electronics 2308A-1HPGGI8 is a 3.3V PLL zero-delay clock multiplier designed for high-speed clock distribution and multiplication applications. It operates within a frequency range of 10MHz to 133MHz, aligning the phase between the incoming clock and output clock to achieve zero delay. The device features eight LVCMOS outputs organized into two banks of four, with separate enable controls for each bank. It utilizes an external feedback pin to synchronize outputs to the input clock, ensuring low jitter and skew characteristics suitable for demanding digital systems.

Feature Summary

• Zero-delay PLL architecture synchronizes output phase with input clock
• Eight LVCMOS outputs distributed across two independent banks
• External feedback loop allows user-controlled delay adjustment
• Low cycle-to-cycle jitter under 200 ps

Applications

• High-speed clock distribution networks
• System synchronization in multi-clock domains
• Digital signal processing hardware interfaces

Procurement Notes

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

Selection Notes

Select this model when zero-delay synchronization is required for frequencies up to 133MHz. Ensure the design supports external feedback connections for proper PLL operation. Verify that the 3.3V supply voltage and LVCMOS output levels match the target system requirements.

Part Context

This component belongs to the 2308A series of clock multipliers, which are engineered for precise timing control. The 'H' suffix indicates high-drive capability, while 'GGI8' specifies the TSSOP-16 package with tape-and-reel packaging. It serves as a specialized solution for reducing clock skew in complex electronic architectures.

Replacement Considerations

Consult official substitution guides for compatible alternatives if this specific variant is unavailable. Ensure any replacement maintains identical pinout, voltage levels, and zero-delay functionality.
