2308-5HDCGI8

Overview

The Renesas 2308-5HDCGI8 is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution applications. Operating within a frequency range of 10 MHz to 133 MHz, it aligns the phase between the incoming clock and output clocks to achieve zero delay. The device features two banks of four outputs each, controlled via select addresses, allowing independent tri-state control. It operates at a core voltage of 3.3V with LVCMOS output types. Key electrical parameters include an output skew of less than 200 ps and cycle-to-cycle jitter under 200 ps peak-to-peak. The component is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay PLL architecture synchronizes outputs directly to the input clock reference
• Dual output banks with independent enable controls for flexible routing
• Low jitter performance with <200 ps cycle-to-cycle specification
• Spread spectrum compatible input support for EMI reduction

Applications

• High-speed digital signal processing systems requiring precise clock alignment
• Memory interface synchronization where zero skew is critical
• Communication equipment utilizing spread spectrum clocking techniques
• Test and measurement instruments needing low-jitter clock generation

Procurement Notes

Verify the specific suffix 'HDCGI8' against official Renesas documentation to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SOIC-16 package. Check for moisture sensitivity level requirements during assembly processes. Confirm availability status as product lifecycles may change.

Selection Notes

Select this component when zero-delay clock multiplication is required for frequencies up to 133 MHz. The 2308-5 variant specifically supports 4x multiplication factors. Ensure the design accommodates the 3.3V supply voltage and LVCMOS logic levels. Consider the thermal characteristics of the SOIC package if operating near the upper temperature limits.

Part Context

This part belongs to the Renesas 2308 series of zero-delay clock multipliers, which are designed to replace crystal oscillators in high-performance systems. The series offers various multiplication factors and output configurations to suit different system timing requirements while maintaining low jitter and skew specifications across commercial and industrial temperature ranges.

Replacement Considerations

Direct replacements must match the zero-delay PLL functionality, 133 MHz maximum frequency, and 16-pin SOIC package. Verify that alternative components support the same 4x multiplication factor and LVCMOS output levels. Ensure equivalent jitter and skew specifications to maintain system timing integrity.
