2308-1HPGGI8

Overview

The Renesas Electronics 2308-1HPGGI8 is a 3.3V PLL zero-delay clock multiplier designed for high-speed clock distribution and multiplication applications. It operates within an input frequency range of 10 MHz to 133 MHz, providing eight CMOS outputs distributed across two independent banks of four. The device achieves zero delay by synchronizing output phases with the input clock via an external feedback pin. Key electrical specifications include a maximum cycle-to-cycle jitter of 200 ps and output skew under 200 ps. It functions on a single 3.3 V supply, drawing approximately 70 mA of operating current.

Feature Summary

• Zero-delay phase alignment between input reference and output clocks using external feedback
• Eight CMOS outputs organized into two independently enableable banks of four
• Low jitter performance with cycle-to-cycle jitter less than 200 ps
• Supports 1x, 2x, and 4x multiplication ratios via address pins

Applications

• High-speed clock distribution in networking equipment
• Multiplication of system reference clocks in industrial control systems
• Clock generation for high-performance digital signal processing architectures

Procurement Notes

Verify component authenticity through authorized channels as this part number 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 existing design specifications.

Selection Notes

Select this component when low jitter and precise phase alignment are required for frequencies up to 133 MHz. Ensure the application supports the TSSOP-16 surface-mount package dimensions. Verify that the system power budget accommodates the 70 mA typical operating current at 3.3 V.

Part Context

This component belongs to the IDT 2308 series of zero-delay clock multipliers, originally developed by Integrated Device Technology (IDT) and subsequently acquired by Renesas Electronics. The series is engineered for applications requiring flexible clock multiplication without introducing propagation delay relative to the input reference.
