23S08E-1HDCGI8

Overview

The Renesas Electronics Corporation 23S08E-1HDCGI8 is a discontinued 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, utilizing LVCMOS input and output types. The device features one input and eight outputs organized into two banks, with a maximum cycle-to-cycle jitter of 200 ps and output skew under 200 ps. It supports spread spectrum input compatibility and offers a 1x multiply/divide value. The component is housed in a 16-pin SOIC package (Code DCG16) with dimensions of 9.9 x 3.9 x 1.5 mm and a pitch of 1.27 mm, operating within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero delay PLL architecture synchronizes output phase with the incoming clock input.
• Supports spread spectrum input for EMI reduction capabilities.
• Provides 1x multiplication factor with 8 LVCMOS outputs across two independent banks.

Applications

• High-speed clock distribution systems requiring low jitter performance.
• Digital signal processing circuits operating between 10 MHz and 133 MHz.
• Embedded systems needing synchronized clock generation from a single reference source.

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to existing stock or secondary market distributors. Verification of lot dates, moisture sensitivity levels, and authenticity is critical due to the end-of-life status. Ensure that any sourced units meet the original RoHS compliance specifications before integration into new designs.

Selection Notes

Designers should consider the 1x multiplication constraint when selecting this part, as it does not support frequency doubling or quadrupling internally. Verify that the system requires exactly one input and eight outputs. For applications needing higher multiplication factors, alternative models such as the IDT2308-2 or IDT2308-4 series may be more appropriate. Confirm that the 3.3V core voltage aligns with the target board power rails.

Part Context

The 23S08E-1HDCGI8 belongs to the broader 23S08 family of zero delay buffers manufactured by Renesas Electronics (formerly IDT). This family addresses high-speed clock multiplication needs where phase alignment between input and output is critical. The specific suffix indicates the 1x multiplier variant in a lead-free SOIC package, distinguishing it from other variants like the -2H or -5H which offer different drive strengths or multiplication options.

Replacement Considerations

Direct pin-compatible replacements are limited due to the obsolete status. Potential functional substitutes include the IDT2308-1 or IDT2308-2 series, provided the 1x multiplication requirement is met. Designers must verify package dimensions and electrical parameters against these alternatives to ensure compatibility with existing PCB footprints and timing constraints.
