23S08-4DCG8

Overview

The Renesas Electronics 23S08-4DCG8 is a 3.3V 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 a fixed 4x multiplication factor. The device features eight LVCMOS outputs organized into two independent banks, allowing separate control via output enable pins. Key electrical specifications include a maximum cycle-to-cycle jitter of 200 ps and an output skew of less than 200 ps. It accepts spread spectrum inputs to reduce EMI and utilizes an external feedback pin to synchronize outputs with the input clock phase.

Feature Summary

• Zero-delay PLL architecture synchronizes output phase with the input clock reference
• Fixed 4x multiplication ratio for frequencies between 10 MHz and 133 MHz
• Eight LVCMOS outputs divided into two independently controllable banks
• Spread spectrum input compatibility for electromagnetic interference reduction

Applications

• High-speed digital signal processing systems requiring precise clock alignment
• Memory interface synchronization in server and storage architectures
• Telecommunications equipment utilizing multi-frequency clock generation
• Industrial control systems needing low-jitter clock distribution

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Review datasheet revisions for any parameter updates or design-in recommendations specific to the DCG16 package variant.

Selection Notes

Select this model when a fixed 4x multiplication ratio is required without external programming. Ensure the application supports LVCMOS voltage levels at 3.3V. Verify that the PCB layout accommodates the SOIC-16 footprint dimensions of 9.9 x 3.9 mm with a 1.27 mm pitch. Consider thermal dissipation requirements as the device draws approximately 45 mA during operation.

Part Context

This component belongs to the IDT/Renesas 2308 family of zero-delay clock multipliers. Variants within this series differ primarily by multiplication factors (1x, 2x, 4x) and package types (SOIC, TSSOP). The 23S08-4DCG8 specifically denotes the 4x multiplier version housed in a standard SOIC-16 package, distinguishing it from higher-drive or spread-spectrum-only variants.

Replacement Considerations

Direct substitutes include other 2308 family members with identical 4x multiplication ratios, such as the 23S08-4HDCG8 for high-drive applications. Cross-reference part numbers like IDT2308-4DCG8 for legacy sourcing. Verify pinout compatibility and electrical parameters before substituting with generic clock multipliers.
