2308A-4DCGI8

Overview

The Renesas Electronics 2308A-4DCGI8 is a 3.3V PLL zero-delay clock multiplier housed in a 16-pin SOIC package. It functions as a clock generator supporting input frequencies up to 133 MHz and providing eight LVCMOS outputs within the same frequency range. The device operates with a supply voltage of 3.3 V and draws a maximum operating current of 45 mA. Key electrical specifications include a maximum duty cycle of 60% and a peak-to-peak jitter of 400 ps. It is designed for surface-mount installation and complies with RoHS standards.

Feature Summary

• Zero-delay PLL architecture ensures minimal propagation delay between input and output clocks.
• Supports high-frequency operation with maximum input and output frequencies reaching 133 MHz.
• Provides eight parallel LVCMOS outputs for distributing clock signals across multiple system components.
• Operates on a single 3.3 V power supply with a typical current consumption of 45 mA.

Applications

• High-speed digital systems requiring precise clock synchronization.
• Data communication equipment utilizing multi-channel clock distribution.
• Embedded systems integrating memory or logic devices with strict timing constraints.

Procurement Notes

The 2308A-4DCGI8 is listed as an obsolete product by the manufacturer. Availability is restricted to existing stock or surplus channels, as standard production has ceased. Verification of component authenticity and storage history is critical due to the end-of-life status. Buyers should confirm the specific manufacturing date code and ensure compliance with moisture sensitivity level requirements before integration into new designs.

Selection Notes

Designers requiring this specific zero-delay multiplier configuration must account for the component's discontinued status. Alternative solutions from the same family, such as the 2308-3DCG or 2308-1HPGGI, offer similar functional parameters but may differ in package type (SOIC vs. TSSOP) or environmental rating. Selection should prioritize verifying pin compatibility and electrical equivalence if substituting with other variants in the 2308 series.

Part Context

This component belongs to the Renesas 2308A series of clock generators and support products. It is functionally equivalent to the IDT2308A-4DCGI8 under previous branding. The part is categorized under Clock & Timer ICs and serves as a specialized buffer/multiplier for stabilizing and distributing clock signals in complex electronic architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available for this obsolete component. Designers should evaluate the 2308-3DCG or 2308-1HPGGI for potential pin-compatible alternatives, though package differences (SOIC vs. TSSOP) require careful mechanical review.
