23S08-2HDCG

Overview

The Renesas Electronics 23S08-2HDCG is a 3.3V zero-delay clock multiplier designed for high-speed clock distribution and multiplication applications. It operates within a frequency range of 10 MHz to 133 MHz, utilizing a phase-lock loop (PLL) architecture to achieve zero delay by aligning the output clock phase with the input reference. The device features eight LVCMOS outputs organized into two banks of four, allowing independent control via select addresses. It supports spread spectrum inputs and includes a test mode for direct input driving. The component is housed in a 16-pin SOIC package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Zero-delay PLL operation synchronizes output phase with input clock
• Eight LVCMOS outputs distributed across two independently controllable banks
• Spread spectrum compatible input support for EMI reduction
• Configurable multiplication factors including 1x and 2x modes

Applications

• High-speed clock distribution networks
• System synchronization requiring precise phase alignment
• Digital signal processing equipment operating up to 133 MHz

Procurement Notes

Verify the specific suffix 'HDCG' against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm that the '2' designation correctly corresponds to the 1x/2x multiplication configuration. Ensure compatibility with 3.3V logic levels and check for any obsolescence notices prior to procurement.

Selection Notes

Select this component when a zero-delay buffer with spread spectrum capability is required for frequencies up to 133 MHz. The 23S08-2HDCG is suitable for designs needing eight buffered outputs with independent bank control. Verify that the 16-pin SOIC footprint fits the PCB layout constraints and that the commercial temperature range meets environmental requirements.

Part Context

This part belongs to the IDT/Renesas 23S08 family of zero-delay clock multipliers. The '2' suffix typically indicates specific prescaling and multiplication options (1x and 2x). The 'HD' denotes the SOIC package, while 'CG' often signifies lead-free and RoHS compliance. This series is widely used in telecommunications and computing infrastructure for clock generation.

Replacement Considerations

Direct replacements include other variants within the 23S08 family such as the 23S08-1HDCG or 23S08-4HDCG, provided the multiplication factor matches the design needs. Cross-reference with IDT original part numbers like IDT23S08E-2HDCG for pin-compatible alternatives.
