23S08E-2DCGI8

Overview

The Renesas 23S08E-2DCGI8 is a discontinued 3.3V zero-delay clock multiplier compatible with spread spectrum inputs. It features one LVCMOS input and eight LVCMOS outputs, supporting frequencies from 10 MHz to 133 MHz. The device provides multiply/divide values of 1 or 2, with a maximum core-to-core jitter of 200 ps peak-to-peak and output skew of 200 ps. Packaged in a 16-pin SOIC (DCG) tube, it operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero-delay buffer architecture for low-skew clock distribution
• Spread spectrum input compatibility for EMI reduction
• Configurable multiply/divide ratios of 1x or 2x
• Single LVCMOS input driving eight LVCMOS outputs

Applications

• High-speed digital system clock generation
• FPGA configuration and synchronization
• Telecommunications equipment timing
• Industrial control systems requiring precise clocking

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to remaining stock held by distributors such as Avnet and Flip Electronics. Verification of lot dates and storage conditions is critical due to the end-of-life status. Standard procurement channels may not guarantee new production units.

Selection Notes

Designers should verify that the 10–133 MHz frequency range meets system requirements. The LVCMOS I/O levels must align with downstream logic voltage tolerances. Consider the 200 ps jitter specification against the sensitivity of connected receivers. Alternative solutions from the Femtoclock family may offer updated availability and enhanced performance metrics.

Part Context

The 23S08 series belongs to Renesas' legacy clock multiplier portfolio, designed for zero-delay buffering applications. This specific variant utilizes a 16-pin SOIC package. It serves as a foundational component for distributing reference clocks across multiple subsystems in embedded electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult current Renesas Femtoclock product lines for functional equivalents with active manufacturing support.
