2308B-1DCG8

Overview

The Renesas Electronics Corporation 2308B-1DCG8 is a zero-delay clock multiplier IC designed for high-speed digital systems. It operates on a single 3.3V supply and features one input driving eight LVCMOS outputs. The device supports input frequencies ranging from 10 MHz to 133.3 MHz, with corresponding output frequency ranges of the same span. Key electrical specifications include a maximum peak-to-peak clock-to-clock jitter of 100 ps and an output skew of 200 ps. Manufactured in a 16-pin SOIC package (code DCG16), it functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero-delay buffer architecture ensuring minimal propagation delay between input and output clocks.
• Eight LVCMOS outputs driven by a single LVCMOS input for fan-out expansion.
• Low jitter performance with a maximum C-C jitter of 100 ps peak-to-peak.
• Operates at standard 3.3V core voltage with a frequency range up to 133.3 MHz.

Applications

• Clock distribution in high-performance computing platforms.
• Fan-out buffering for memory subsystems requiring low skew.
• System synchronization in telecommunications infrastructure equipment.

Procurement Notes

This component is identified as obsolete or end-of-life status in public distributor records. Verification of current availability requires checking authorized channels for remaining stock or alternative sourcing strategies. Compliance details indicate lead-free construction (Pb-Free Category e3 Sn) and adherence to RoHS3 standards. Moisture Sensitivity Level (MSL) is rated at 3, requiring appropriate handling during storage and assembly processes.

Selection Notes

Select this part when a single-ended LVCMOS clock source needs to drive multiple synchronous loads with tight timing constraints. The 1:8 ratio suits designs requiring moderate fan-out without differential signaling complexity. Ensure the design environment stays within the 0°C to 70°C operating range and that power supply noise does not exceed the specified jitter budget.

Part Context

The 2308B series belongs to Renesas' family of zero-delay clock multipliers and buffers, originally developed under IDT branding before acquisition. This specific model variant utilizes the DCG16 package code, denoting a 16-lead Small Outline Integrated Circuit with a 1.27 mm pitch. It serves as a legacy solution for systems transitioning from older clock generation methods to more precise PLL-based distribution networks.

Replacement Considerations

Public records list the 2308B-2DCG as a related substitute within the same product family. Verify pinout compatibility and electrical parameter alignment, specifically output count and jitter specs, before considering any cross-replacement. No other direct equivalent part numbers are confirmed in the provided data.
