23S08-4DCG

Overview

The Renesas 23S08-4DCG is a 3.3V Zero Delay Clock Multiplier designed for high-speed digital systems. It accepts LVCMOS input frequencies between 10 MHz and 66.6 MHz and generates eight LVCMOS outputs ranging from 10 MHz to 133.3 MHz. The device operates with a core voltage of 3.3V and features a maximum center-to-center jitter of 100 ps peak-to-peak. It utilizes a 16-pin SOIC package with a pitch of 1.27 mm and supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Zero delay buffer architecture ensures minimal output skew of 200 ps.
• Supports frequency multiplication ratios of 1x, 2x, and 4x via hardware configuration.
• Compatible with spread spectrum clocking inputs for EMI reduction.
• Provides eight buffered LVCMOS outputs driven by a single LVCMOS input.

Applications

• High-speed data communication interfaces requiring precise clock distribution.
• Memory subsystems needing synchronized multi-output clock signals.
• Industrial control systems utilizing standard logic families.

Procurement Notes

Verify the specific suffix '4DCG' against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm that the 16-pin SOIC form factor meets PCB layout requirements. Check current lifecycle status as this component may be subject to discontinuation or replacement by newer series.

Selection Notes

Select this part when a single source clock must drive multiple loads with zero propagation delay relative to the feedback loop. Ensure the input signal amplitude matches LVCMOS levels. Verify that the required output frequency does not exceed 133.3 MHz given the 66.6 MHz maximum input constraint.

Part Context

This component belongs to the 23S08 family of zero-delay clock multipliers. It serves as a buffer and multiplier for system clocks, distinct from programmable synthesizers like the RC223 series. It provides deterministic timing relationships essential for synchronous digital designs.

Replacement Considerations

The 23S08B-4DCG is a verified functional substitute within the same family, offering identical electrical characteristics and pinout in the same SOIC package.
