2308B-1DCG

Overview

The Renesas Electronics 2308B-1DCG is a discontinued 3.3V Zero Delay Clock Multiplier housed in a 16-SOIC package. It features a single LVCMOS input and eight LVCMOS outputs, supporting frequency multiplication ratios of 1x to 8x. The device operates within an input and output frequency range of 10 MHz to 133.3 MHz. Key electrical specifications include a maximum peak-to-peak clock-to-clock jitter of 100 ps and an output skew of 200 ps. It functions with a supply voltage between 3V and 3.6V and supports an operating temperature range from 0°C to 70°C.

Feature Summary

• Zero Delay Buffer architecture ensuring minimal propagation delay
• Eight LVCMOS outputs with configurable multiplication ratios (1:1 to 1:8)
• Low phase noise performance with 100 ps max C-C jitter
• Single-ended LVCMOS input/output interface

Applications

• High-speed digital system clock distribution
• FPGA and ASIC clock generation
• Telecommunications equipment timing
• Industrial control systems requiring low-skew clocks

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to the secondary market or existing stock at authorized distributors. Verify moisture sensitivity level (MSL 3) and lead-free status before procurement. Ensure compatibility with current supply chain constraints due to end-of-life status.

Selection Notes

Select this part for applications requiring a single-ended LVCMOS interface and up to eight buffered clock outputs. It is suitable for designs needing frequencies up to 133.3 MHz with strict jitter requirements. Consider the 2308B series variants if different multiplication factors or package options are needed, noting that all related parts share similar electrical characteristics.

Part Context

The 2308B-1DCG belongs to the IDT/Renesas 2308B family of zero-delay buffers. These devices are designed to eliminate clock skew by feeding back the output clock to the PLL input. The 'DCG' suffix indicates a 16-pin SOIC package with lead-free termination. This specific model represents a standard commercial grade version within the broader 2308 series portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, engineers should evaluate newer generations of clock multipliers from Renesas or other manufacturers that offer compatible pinouts and electrical specifications.
