23S08-1HDCGI

Overview

The Renesas Electronics 23S08-1HDCGI is a 3.3V zero-delay clock multiplier and buffer designed for high-speed clock distribution applications. It operates within a frequency range of 10 MHz to 133 MHz, utilizing an internal phase-lock loop (PLL) to synchronize output phases with the input reference clock. The device features eight LVCMOS outputs organized into two banks of four, allowing independent control via select addresses. It supports spread spectrum input compatibility and includes a test mode for direct input-to-output driving without PLL intervention. The component is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay operation aligns output phase with input clock using external feedback pin
• Eight LVCMOS outputs distributed across two independently enabled banks
• Spread spectrum input compatible for EMI reduction
• Test mode allows bypassing PLL for direct input clock monitoring

Applications

• High-speed clock distribution networks
• System synchronization requiring low skew
• EMI-sensitive digital circuits

Procurement Notes

Verify the specific suffix 'I' against official Renesas documentation to confirm temperature grade or tape-and-reel configuration, as standard listings may vary by packaging type. Ensure the source document explicitly identifies this part number to avoid confusion with similar variants like the 23S08-1HDCG.

Selection Notes

Select this component when a single input clock must be multiplied or buffered to eight outputs with minimal skew. Verify that the system requires 3.3V operation and LVCMOS output levels. Confirm that the input frequency falls within the 10 MHz to 133 MHz range and that spread spectrum compatibility is required.

Part Context

This part belongs to the 23S08 family of zero-delay clock multipliers. It shares core functionality with other variants such as the 23S08-2HDCG but differs in multiplication factors and drive strength. The '1H' designation typically indicates a specific multiplication ratio and high-drive capability compared to standard versions.

Replacement Considerations

Direct substitutes include other 23S08 family members like the 23S08-1HDCG if packaging differences are acceptable. Cross-family replacements require verifying PLL architecture and output voltage compatibility.
