23S08E-3DCG

Overview

The 23S08E-3DCG is a Renesas Electronics clock multiplier designed for zero-delay applications. It operates on a single 3.3V supply and features one LVCMOS input driving eight LVCMOS outputs. The device supports an input frequency range of 10 MHz to 133 MHz, with corresponding output frequencies in the same range. Key electrical specifications include a maximum operating current of 45 mA and a center-to-center jitter of 200 ps peak-to-peak. It 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 clock multiplier architecture ensuring minimal propagation delay.
• Single 3.3V power supply operation with low current consumption.
• Eight LVCMOS outputs driven by a single LVCMOS input.
• Supports input and output frequencies from 10 MHz to 133 MHz.

Applications

• General-purpose clock distribution in digital systems.
• Buffering and multiplying clocks for high-speed logic interfaces.
• Embedded systems requiring precise timing synchronization.

Procurement Notes

This component is identified as obsolete or end-of-life (EOL) by major distributors such as Mouser Electronics. Availability is restricted to existing stock or surplus markets. Verification of authenticity and storage history is critical when sourcing from non-authorized channels due to the discontinued status.

Selection Notes

Select this part for designs requiring a fixed-ratio clock multiplication with zero-delay buffering at 3.3V. Ensure the application fits the 10-133 MHz frequency range and LVCMOS voltage levels. Consider the SOIC-16 package constraints and the 0°C to +70°C operating temperature limit during PCB layout and thermal analysis.

Part Context

The 23S08E-3DCG belongs to the 23S08 family of zero-delay clock multipliers. It serves as a legacy solution for clock generation before the widespread adoption of programmable PLL synthesizers. The 'E' suffix typically denotes specific environmental or packaging variations within the Renesas portfolio, while 'DCG' indicates the SOIC-16 package type.

Replacement Considerations

As the 23S08E-3DCG is obsolete, direct replacements may be limited. Review the 23S08 series variants (e.g., 23S08-2HDCG, 23S08-1HPGG) for pin-compatible alternatives if available. Modern ultra-low jitter synthesizers like the FemtoClock 3 series offer superior performance but require different interface configurations.
