CDC2351MDBREP

Overview

The CDC2351MDBREP is a single fanout buffer from Texas Instruments designed for clock distribution. It provides a 1:10 input-to-output ratio, converting one LVTTL input signal into ten LVTTL outputs. The device supports maximum operating frequencies of 100 MHz and functions within a supply voltage range of 3V to 3.6V. Housed in a 24-SSOP package with a width of 5.30mm, it is rated for an extended industrial temperature range of -55°C to +125°C. This component serves as a dedicated clock driver for digital systems requiring signal splitting.

Feature Summary

• Single circuit configuration providing 1:10 fanout capability
• Supports LVTTL logic levels for both input and output signals
• Maximum operating frequency of 100 MHz
• Operates on a 3V to 3.6V power supply
• Extended temperature range from -55°C to +125°C

Applications

• Clock distribution networks in embedded systems
• Signal buffering for high-speed digital circuits
• Fanout expansion in communication equipment

Procurement Notes

Verify the specific ordering suffix MDBREP against official Texas Instruments documentation to confirm the tape and reel packaging format. Ensure that the 24-SSOP physical dimensions match the target PCB footprint requirements. Confirm that the LVTTL input/output specifications align with the system's voltage levels before procurement.

Selection Notes

Select this component when a single clock source must drive ten distinct loads using LVTTL standards. The 100 MHz frequency limit defines the maximum operational speed. Verify that the 3V to 3.6V supply range matches the system power rails. The -55°C to +125°C rating is suitable for harsh industrial environments compared to commercial grade parts.

Part Context

This part belongs to the clock buffer and driver category within Texas Instruments' portfolio. It functions specifically as a fanout buffer rather than a programmable clock generator or synthesizer. The 24-SSOP package distinguishes it from larger SOIC or smaller QFN variants in similar product lines.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family that offer different packaging options such as tube or cut tape if reel quantities are not required. Verify electrical compatibility regarding the 1:10 ratio and LVTTL levels.
